My hand hurts just looking at this x_x Did you have some plan for the placement of the objects in the clutter or did they just happen naturally? There's a bit in the middle which seems to bulge out of the page, that looks pretty cool. It looks great anyway, looks like something a viewer could spend ages in front of seeing what they can find :)
I really did not have any sort of plan doing all the clutter. I did start at the bottom and worked my way up. The are that seems to bulge is probably from 1 day of drawing. I could do about an inch up each day.
