Interest + Price check?

I'm relatively new here, but I've come to the conclusion that currency would definitely help me out. As such I have no idea how the conversion is for purchasing art using the website's currency and I'm kind of inclined to just open a shop that's PWYW.

You've got some gorgeous work! I'd definitely be interested c: Not sure on what to price your work out though, pricing is always the hardest part ;3;
