I think the design is pretty, you could use some other colors to make it more colorful. Also, if you want smoother lines, you can find a tool in the size of your brush section, there's a bar that says smoothing or something like that. You could use it and set it on something and it goes slower so your lines come out smoother ^^. I think the design is very pretty though ^^ <3
