I've made this new portrait as a test to my tablet, i think the tablet is helping a lot but i have a lot of improvment to make, thanks to Maaia for helping me a lot on this ;3
Might I suggest experimenting with a bit of a highlight to the horns? I can tell you're going for a more matte look, but forehead horns are hard. They're also typically distinct enough of a feature to warrant a bit extra highlight without having to re-shade the whole image.
...Though this is a tricky angle, and you might have tried that, and found it looks better matte. Never an easy call, but I trust your judgement as the artist.
