Thanks for the suggestions guys. And the angle of the speaker is meant to be towards you, but it was hard to get it to appear that way. I will put a link to my reference.

I think the overdithering kills the metallic-specular materials of the original a bit. Otherwise quite good for a first one.

Dunno if it's in the rules or not but it's a practice to state references here.

I really like it. The unfinished spots (white) make it look different and unique from others. :)

The angle of the speaker looks a bit strange. At first glance it looked like it was turning towards me, but it seems you intended it to be facing away. Also, the white pixels on it look a little strange. Other then these problems though it looks very nice, especially for a first piece.
