EEEEH OMG OMG OMG this must be the fastest fanart I've ever had; in two days! She looks absolutely GORGEOUS, and you drew her design so perfectly !! Aaaah this fills me with joy !;33; I'm so so happy you drew her, thank you so much !! this was so unexpected !
Just remember, don't expect to instantly be amazing. You have to train your hands to do what they need to do, and they're not always cooperative. The best thing to do is draw every day, develop your own style, and have fun with it! You have a drawing tablet, don't you? Unfortunately a lot of effects like painty effects come from pen pressure, which you can't get in a mouse.
