I still don't know if you are a troll or not, I think you are something between 4chan, NG and "Yeeeh!" you know? But anyway, I'm here to review your art not you :P
So yeah, the proportions may be good but the sun shines from the background to the dinosaur, your shadows aren't all accurate, the cloud needs to hang a bit higher or put it away at all, it's unclear if it's a normal cloud or just smoke from the Dino's nose, who is then maybe a drake? Just take the cloud away and it should look fine.
The birds are 'nice' but those things kinda remind me on my child drawings where you use to put the sun always in the corner with some birds flying into it like fecking Icarus. If you put more detail to the birds, make 'em bigger or something like that, it should look awesome. Although your style is more derpy, you should take a look at actual pictures of that flying dinosaurs and study them. Draw them in your style then you'll be able to make that picture epic (http://pichost.me/1348304/)
Well all I have to say is, that you done a nice job but you are way to go to make that picture awesome.
3/5 Stars
Carry on! I like 'yer style
