Up

Another tree..........................

[RArcher]

This one is missing what the last few were also missing - Light.  Don't be afraid to up the exposure.  The tree is pretty cool though.

I liker the ground arrangement. Just the right amount of coverage.

[yossam]

Light..............give me more light. 

[Bjur]

The bush itself and it's base fits the ground and it's vegetation/grass very well!

Looks nice. Lighting is better, but now the lighting is a bit harsh. Try some method of scattered defusing, and you may reach Zen.

I like the last one. The sky with this clouds are very nice and realist !
