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.

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).

And one without the borders.

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.
Looks good. I like the look of the first one best, for some reason.
EDIT: I just realized why. Because it's in black and white, and only a Sith deals in absolutes.
I still can't draw at all. Especially people.

You should have more confidence in your own ability, you're actually quite good. You should be more positive about your drawings without coming across as being a show-off. Personally, I thought the drawing of the guy shooting himself in the head was really good, particularly the gun and head. The splatter of brain and blood could do with some touching up but overall it's a good drawing. I'd love to see more of your drawings.
I'm studying Arts, and I must say, You have an expended varity of imagination, or however I must say it!
Spend some more time at making the pencil version, I usually spend around 4-5 hours on the pencil!
