Looks great! Those mushrooms are noticeably evenly laid out at this zoom, though. I'm not sure how obvious the effect is in game, but with the full picture it's obvious they're just plopped down at a more or less even spacing to fill in the purple... mist? Again, not sure how it'd look in game, but you might consider clumping them up a bit.
Otherwise, real snazzy. It is a bit hard to see any detail at these zooms, though! Post some close ups!
