Hmm... Now I think "mistake" isn't the right word. I think it is something between "mistake" and "wish of fate"....
The third bush texture is just a rock ;)
The second bush is just a mess that looked good with a particular pallet. About "mistakes", this word fits the texture of the second bush perfectly because I tried to apply the technique from one tutorial but I started to do it wrong and got this....
I would like to create some rocks in another style but I can't. I tried to do it many times but I get everything but not rocks... I don't know why but some things just happen... They draw themself
