These are some nicely done trees.

Thank you, I'm glad that you like.

The texture is definately a good bit of work all on its own I'm quite impressed!

nice, like the first one the most! :)

Submit them to the challenge, hehe

Thank you for your nice comments

@ failurboy: Busy grounds are problematic indeed. Maybe I will improve it someday

 Beautiful texture on these!

 Love the twisting trunks.  I bet the spindly branches would not look good over a busy ground, but against a stark sky they would look great (awesome for a sidescroller).

beauitul job. Second and third are very nice especially, such lovely textures. Well done!
