This is Bunbun Firerabbit (last name may be updated though). A Neutraninjian pet of Kao's who's always playing with him when he's alone.
This image is the first image I've colored entirely on my phone. It took a week due to the learning curve, but with what I learned from the experience, it's actually pretty smooth. Still torn for which art program is best on Android as they all have their ups and downs (and I don't mind paying for more utility long as the paid version isn't also limiting... so ArtFlow is out of the question. 16 layers will get used VERY fast). I did this in Medibang though, which I really like all around once you get past the UI being somewhat cluttered. There's also ibisPaint which I do like, but the default brush is kind of a pain to work with.(I like a smooth antialiased brush for line art.). Still, for my needs, either is good enough. Haven't tried Adobe Illustrator yet, but apparently some features on it don't work on Android.
Anyway, I'll probably be doing digital a lot more often now thanks to this. I'll still do traditional when I feel like it though as having physical drawings of the character is good for back ups.
