Okay another criticism from me
First-Up: Good start, nice color choices, looks pleasant to the eye.
Now on to the real meat
Firstly, the mountains still look more like flatlands. I think you should raise them quite a bit, so they are clearly visible. Currently - to me - they look more like dust-plains.
As for woods, maybe you could try the brush I use for my woodlands (Photoshop CS3)
Data for the brush can be found here (klick me!)
