Coloratura Render

I'd add a curve to the eye lashes, they look really unnaturally spikey there,

I'd also recomend softening the iris and the highlights by a few (voxels?), her eyes at the momen are sharp like the show where as the rest of her is silky 3d

No idea how you've done the hair and it's probably just a texture, but you could make the hair look a decent bit nicer by actually have the indents be 3d, for example where the hair faces us we can clearly see notably deep indents but where the
hair is coming nearly straight at us there is no depressions.

The ears should probably be slightly deepended and finally consider making her cheeks a bit chubbier as her face is *very* round.

Tiny nit picks, the streaks of colour and the streaks indicating where her hairs are don't always line up (suggesting her hair colour has changed multiple times)
how the hell is she so adorable?

It's still the top 2/3 of the best 3d models ive ever seen for mlp anyway so please keep up the work
