Wow, your best piece yet. Only thing I suggest is that you add AA on the rays of light.

Profound, but I don't like the rocks.

awesome, but you could have put AA on the lines.

awesome, dude

Your style has become very recognizable. It is very interesting and nice.

But the lightning sucks...

 So stylish! The clouds are great. =)

Nice, I like how you have done the composition in these last two pics. One thing.. maybe you could try to give the camels different silhouettes to make them more different..for example make one's foot out like it is walking up the mountain? If you like the idea.

I love that lightning on the rocks :D

Colors are ever so slightly boring, but nice piece :)

I noticed that you almost always go for extremely rectangular

The people and llama things walking up the hill could do with a tad bit of AA and the orangish yellow color is not well picked or used.

Aside from those small nitpicks, this is really good :)
