Thank you for the kind words and I'm happy to hear you like the game so far.
Actually most of the art in this game has been commissioned, though I go myself and correct mistakes, edit parts, add details, etc.
Yeah, I may do some art tutorials one day - nothing planned though. Though, tbh I am only an armature artists and not a pro by any means. I only know the absolute basics and consider myself still a beginner/intermediate artists.
Best thing is just to get stuck in and practice. Just get drawing and painting.
Wish you the best of luck!
