Welcome to unity ninja! <from a fellow newbie>
I'm also a beginner in unity and when it comes to 2D drawing, I'm still studying Life and Figures.
Wow your art is superb and the youtube channel is great! Kudos to you my friends ^_^, do you have a deviant account too? If not then, I would really suggest you check out it out since it's a very nice community for artists and designers alike.
I hope to become a great company/acquaintance/friends with you.
I'm your 278th subscriber yay ^_^. Your art style captivates me and well, I hope to see more of your works in the future. Take care
