Thoughts and critiques? Be blunt. I have a thick skin and I want to improve. I'm not a fan of the sparkles. I wanted to tie in his pink hooves somehow (yes, I actually painted them with pink biodegradable glitter and hoof conditioner in RL...) but they just seem awkward. 

Also, with my dabbling, what should I start my pricing for premades? I've been trying to look around to compare, but I cant really get a good grasp on what to charge. I can't do any crazy detailed work just yet as I'm just now getting back into it. 

I think you did pretty good! Give yourelf some grace getting back into it. For the BG try using a layer mask and the gradiant tool instead of the eraser tool. It will be a little more even to fade out the edges and easier to control. Also make sure and duplicate your layers as you go in case you mess up and can't go back. I have learned that the hard way. lol I think if you got rid of the sparkles and just lean into the hooves maybe brighten the color of them. I don't think they will stand out on thier own at all! If you really want to add the color in somewhere else you could try a low opacity text glow/shadow around some of the words with the color. 

Pricing is hard, especially starting out but you could try auctions, set an AB you think is fair by looking around at other stuff for sale. They are pretty dry right now though so prices may get inflated with everyone just wanting to get something. But just put it up and see what happens. Another route is to start offering at a low price, like 20/25 mill, and if you get a lot of orders and happy customers at that price you can bump them up as you see fit. With both ways, AB in auctions and order price, if you put out a number and no one buys/orders you know you are asking too much at that point so you go back down to what was selling. It's a balancing game.
