Ok darker outline and they are all from a 45 degree angle It must be because of the light lines that you can't see it though I'll update the outlines and tell me if perspective is still off.

Nope, I think you should be using greater contrast between colours and the type of dithering you're using isn't doing you any justice, I played with your thing quickly and with a few quick adjustments it came out alright.
I really on played with the top surface and top draws. You could benefit from adding some kind of texture to the wood as well.
