Very good so far!  Some points:

• The height from the floor to the top of the counters looks to be too short for any standard kitchen.
• Try rounding the edges of the counters - you'll notice that in real life, no object has a hard 90 degree angled corner.
• Try adding some more items to the kitchen to liven it up a bit.

Your modeling looks solid however!  Where it goes from here will depend on texturing and lighting.

 It's good however a few pointers;

• Make the room higher and like TheProducer said, raise the hieght of the counters.
• I don't know if it's like that but the stove light thingy may want to be closer to the ceilling. (Excuse my spelling)
• Door hieght needs to be higher.
• Smoother corners like TheProducer stated.
• When it's all done, use softer shadows :)

Else it's all good.
