I have another question, now that I've made a few for my own use -- what's the best way to do jungle trees? My grass looks pretty good, at least to me, and I just added a pretty nice ocean layer, but the trees for this tutorial look deciduous instead of tropical. Most of the jungle tree patterns I find are profile rather than top down.

Guess I should show my latest work:

Looks like I could fill in a little more of the ocean up the side, now that I see it again.

Thanks in advance.
