No problem! Ah, I missed the 4 colour deal. Now it's kind of up to you, really. To make it more polished and add some AA you'll probably have to change your pallete and it might sacrifice some of its vibrance. But the colours are nice and it might knock some of its charm away if you go for a safer combination.

And thanks man. That's nice to hear (:

This will get to background of a beautiful landscape. Nice colors, I loved the trunk!

 Thank you for the feedback Opacus! I agree that the leaves need some serious cleaning up. About AA, do you think I should add more colors to the picture? My challenge was to do a tree in 4 colors. Maybe I should adjust the colors so that two of them are more similar and use one of them for AAing? 

Also I went back and looked at your tree from 2007. Wow! Even if it is an old piece to you, it's certainly an inspiration to me, as is the rest of your gallery. 

A little number of colors, but very nice result. 

Really enjoy the colour choice!

Opacus couldn't have said it better.

The basic forms and colours are all great! You should really give this some more attention, though. You could add a lot more refinement and detail to the leaves especially. The tree trunk is slightly too detailed compared to the rest, though that could also benefit from some AA. That all said: I really like this. Reminds me of my own tree from way back. It has a lot of charm and some really cool forms. I especially love the way you did those vines. 

 This is very well done! Congrats!

 it is nice
