Dear Sunny is as bright as she should be. She's earned it, if anything.

I do really like how the wing effect turned out, even with the powerful brightness. The volume of her mane and tail reaching princess levels looks quite appropriate, too, given how she is here. While her rear hooves could've used the nice regalia boots she got on the front here, and perhaps her armbands could've been worked in as well somehow, with the same going for the rather detailed front piece she has on her dress in her human form, overall you managed to preserve the effect quite well. One other thing needing mention is the visually apparent length of her legs - her front legs look shorter than her back at the angle she's posed, which does spoil the effect somewhat. Still, you did very well on everything starting with her golden collar piece, regarding her hair and the effects.
