Q : What applications do you use?
A : For the most part I use Autodesk Sketchbook! For things like pixel art I use MediBang, and lately have been trying to use After Effects to do fun idle animations.
Q : Do you use a custom brush set?
A : Not really, I use the felt-tip pen with hard edges usually.
Q : Is art consistency important?
A : IMO no matter how many styles you believe to have there's always a consistency! Maybe in the line work or coloring, etc but I wouldn't say it's all that important.
Q : Do you accept payment through in app purchases?
A : Yes! Preferrably payment can be used for some of my living expenses, but currently I only accept IAP for Sky: Children of The Light
