The topic title is self explaining. I haven't drawn in many years, so that might explain if it looks bad.
It took me about 1 hour to draw this pencil one.
(direct link)Then a "colored" one (not really colored, just gradients here and there, still took me about 4 hours to do this since I'm bad).
(direct link)And one without the borders.
(direct link)I know about some minor errors (two uncolored 'vines'), if you find something bigger go ahead and tell.
If someone cares, it's not supposed to be concept art, but a pre-rendered "map" scetch (like in Final Fantasy IX), and it's a bunch of huge trees and roots the player where the player can run around.
