Here is an updated version with new drawer design. The drawers themselves are triangular shaped to increase their capacity, and the "drawer" closest to the user is a pigeon-hole, with a sliding fake drawer-front (It slides to the left hand side, under the desktop) This removes the awkward drawer position when opened, as well as giving the user more freedom of movement.
The pigeon-hole can accommodate A4 sized paper and slightly larger, because the drawers are not wide enough for that at the far end.
I've also included two simple biped figures to give it a better sense of size (I know bipeds are not 100% accurate, but they are close enough for this task). The workspace user also shows that the concern for getting a dirty shirt is not so much a threat, since the elbows and arms are not near the whiteboard at all in a normal usage scenario
I've also given the more metallic green a go, it looks better, but I do not think it is there yet.
This a test of another colour scheme suggested by someone
