The clouds does maybe needs a little to be more like the pony, but not much.
The colours of the sky is really good. The stars are also very good made.

It's a very awesome lineart you do, and it's not easy to lineart to me though.

It's a very beautiful art, and you might be very proud of it.
You gonna go even far, i'm sure about that.
I don't have much more to say.
