I like 3 best too, 2 if all the other graphics were VERY geometric.
And if I was using those other graphics, I would have copied the bush, flipped and merged a top and bottom out of those.
ANd Tekniko, if you meant for your signature to show the graphic, make the IMG tags lowercase. The signatures don't like uppercase bbcode.
Edit: you edited while I answered. I like that much better. <img src="smileys/smiley32.gif" border="0" align="middle" />
Now you should do the dirt spots with shadows to match the swirls in the tree, that would look cool.
