Thanks for the comments, and advise.

BTW, the white things were supposed to be meteors, but I guess i didn't hit the spot close enough. But I think I'm getting better, even it is a very slow process. :)

Nice, and nicer at 200%.

A few things maybe: the whitish 'jets' looka bit random and too light (and, what are they?); the mountain outline intersects the dino in a confusing way, looks like a mouth; you might lower it. The dino's shading texture is nice, but could use more contrast.
