MLP OC - Nebula

Any feedback, constructive criticism, advice, tips, etc would be highly appreciated.Just finished designing and illustrating my OC, it's my first attempt at visual digital art from scratch.Her name is Nebula. A scientist/tinkerer at heart, but is kind of socially awkward & reclusive.Still gotta work on a proper backstory, but I wanted to finish her design before working on that. (If you saw the previous iteration, I deleted it, it was the wrong version before the last few edits.)
