***Added a 3rd example please check(Im proud of it!)***

The only art I've done is for contests but I've been thinking of opening a shop to earn some extra ebs. I need help on making prices for them/critiques/advice for managing an art shop. Like what should I charge extra for, when should I request payments, any bad experiences I can learn from. Pretty much any opinions are greatly appreciated:)

OK! I made another piece and tried to listen to all of your suggestions so Id love to hear your opinions one more time. Also what you would pay for this one. I think it is much better quality than the previous two:) I stayed up all night making this one I was so excited how well it was turning out!

50-65k for sure

I would also add a bit of a glow around the horse to add more focus onto it. And I would blur out around the horizon of the BG. But those are just my opinions:)
