This is a kitchen I have designed for a client.  The images are preliminary for review only as the client will make changes.  Take a look at them and give me your honest input.  I've found some really obvious mistakes which I will fix on the next go-around.  Everything is 100% Podium with the PP is correction for perspective crop with PS.  Thanks ahead for all of your input.

These are good renders! There are improvements you can make which I have outlined below, but the most important thing to note is the lighting.

We do not see the world as it really is. Our eyes perform a continuous realtime adjustment of exposure and levels for every single static viewpoint, and our brain in effect equalises what we see to avoid things that a camera would capture as over and under-exposure, almost like an HDR tonemapping adjustment stitching together individual frames in a movie.

Professional photographers often used bounced flash to increase brightness.

The significance of this is that our render engine tries to render things realistically. If you photographed this room in reality, in the form that it is constructed, you would get something not entirely unlike your render. Except that it would appear brighter in reality, because of the correction that our brain does.

So we have to do stuff to our images to in effect mimic the adjustment that is done by the brain.

There are a number of ways we can do this in Podium. First of all we have the interior brighter preset. This boosts lighting levels in an attempt to get fairly close to how we perceive dark rooms in reality.

We can increase the Sun Intensity and Exposure using the sliders. These things should improve things for most scenes.

The next thing you can do is to place a large (slightly smaller than the extents of the walls) 100% transparent invisible LEM with a very low power setting behind the camera. This simulates the effect of light bouncing around the space from behind the camera. It should not be strong enough to cast any noticeable shadows. That usually works very well.

The next thing you can do is add invisible LEMS outside the windows, slightly smaller than the window openings. That boosts lighting in a scene in a very natural way, and it's what professional visualisers do.

In terms of improvements to your scene:

1. Always compose the camera angle of your scene. If you want images that look like photographs, you need to take them as photographers would. That means composing your views, standing on the floor, and pointing the camera straight ahead. All your images have strange camera views almost like the viewpoint is too high, the field of view too large, or the camera pointing sightly upwards. The last photo looks like it was taken by a giant with no idea how to take photos [smile]

2. That sink and kitchen tap are not right. The tap would most likely be chrome, brushed stainless, or plain white. For chrome, use a base colour of charcoal and set reflectivity to around 60%. If it's white, reflection should be maybe 5% and blurred. If it's stainless, use a texture from the browser, and try setting reflection to maybe 10-15% depending on the angle. That sink needs to be white, with reflection of maybe 10%. I've never seen grey porcelain...

3. Download Podium Extras from here, and use the Nudge tool to elevate the furniture and skirting (base) boards. This simulates the subtle contact shadows that you get because almost nothing is perfectly square. Almost everything has slightly rounded corners, which means that at the point of contact of two surfaces that are not specifically sealed, you will get a fine shadow line.

4. Download the Roundcorner plugin and use it on all your worktops. Don't go overboard on the number of rounding segments, because it will can massively increase your polygon count, and slow your render down. Then apply your texture properly around the edges, and smooth the geometry. That will make a lot of difference and add realism.

Once you start to incorporate these things into your regular workflow, you will find that gradually your level of realism will increase, and you won't really notice the additional time spent. [smile]

Took a couple of your suggestions and made some revisions.   Since these renderings were for preliminary review I did not want to get into to much detail until all selections were made.  Still waiting on them...however, I changed the sink and faucet materials...believe it or not I used the same material on the faucet and sink as the appliances.  That farm sink is brushed SS.  I'll work on that later.  I like the gorilla comment...had to get up on a stool to get a good shot of the desk so the client could see it.
