I just finished a painting related to the premier myself, actually!

You did very well on this one, especially with the metal rendering. It looks very convincing.

The one thing that kinda sticks out to me is the low saturation of the fire or w/e surrounding Celestia.

I feel it could've been upped a little bit, but I'm assuming you didn't want it to take all the focus.

Nicely done and it fits together with the Nightmare Moon counterpart.

With these new episodes coming we're bound to get sudden bursts of inspiration
