Ryan,
small points really, but important nonetheless.
Nice linework generally in your illustration, but:
1. Take a look at a book (or website) on perspective. There's some really simple rules that you'll soon pick up and can apply. (Yours is not quite there yet).
2. Be a wee bit more observant. Okay, there's a load of trees on the Hole. Many of them are coniferous (big, dark green pointy ones). You've only drawn deciduous-looking ones(round, curvy stumpy ones). Would be more realistic (and, much more importantly, demonstrate your observative powers) if they'd been more correct.
I agree with the other guys. More info on small scale design elements would be better. A good sketch and/or contour plan of the green complex would be very valuable!
Keep at it though!
FBD.
