Come on man, i think its obviously supposed to be cartoonish.
For me the textures let it down. Particularly the wood texture and the direction of the grain. The beam in the roof at the far wall especially. I was also wondering what the helmet and the anchor are made out of? it looks like egg shell with ink splats all over it.

The style of the scene is fun and i think the lighting and over saturation of the textures compliment this. Although i would imagine the light source in the celling is perhaps unnecessary, and may be a reason why dave thinks there are a lack of shadows.

The modeling reminds me of monkey island or something similarly family friendlyish, however i think the radio is a little under designed and could do with some more work. The map picture frame could also do with some joints. Its unlikely to be one piece of wood.

also is it just me or is the antenna glowing slightly?

nice tho... a character behind the desk would really finish it off.
