Ah thanks guys.

I always found that modeling nature (especially trees) is among the most difficult things to do.
Yeah I reckon, but this was actually quite easy to do.
What I did was create a rectangular prism length 128, height 64, width 1 with 4 horizontal/vertical "segments" so each face was cut 4 times horizontally and vertically. Once I removed the polygons on the sides (leaving only the front and back face), I essentially had the equivalent of two displacement surfaces back to back. I moved the vertexes around a bit to make it bumpy and applied the UV map to it. I then duplicated that object and moved/rotated it.
That was for the main part, I did that same process to the grass like growth on the sides of the model except I duplicated it more times and the rectangular prism was alot smaller (I think it was height 48, length 16, width 1).

I think I would have set each layer row a little closer together and rounded off the corners so that it minimizes the chances of seeing the straight-on side view of the thinness of the polygons.
Ah, good idea, I'll be sure to do that next time.

Maybe create your own skin to make it completely yours.
Yeah for sure, the next one I make I'll use my own texture. I actually started to make my own texture but it was taking along time and I wasn't concerned what texture I used for this practice model. If I had a better source photo it would have been much quicker, I think I'll take my own photo next time.

are you gonna release it?
Well I wasn't going to but I guess I could upload it as a download here.

And how much $ for an arbutus tree

Hehe, I don't think I'm quite close to modeling a decent tree yet but when I am I guess I could make a free one for you. But if you want one now you can always buy one from somewhere like Turbo Squid and compile it for the Source engine.
