wow, great job! I just think that they look too opaque, i mean, you can see through most trees, well through the leaves atleast.

All this green background and tree style reminds me of Final Redemption website...

heheh, im with gassie, i was fooled into thinking it was a kon tree like those on his site at first. I think its because you both are going into gross detail to pixel every little leaf :).  I like the third one in the most out of the bunch. its got a little extra spunk to it. The trunk on it is well formed. digging through old work is nostalgic, eh?

This trees rock. I have the last one in my references for ages. For some reason I thought it's Alex Hanson's art :)

I really like the last one from right to left :D
