can you give me some directions? I'm not very familiar with adobe illustrator and I'm not quite sure how to tighten up my lines (I meant it to be sketchy, but maybe it would be better clean?)
I think you have a good balance of sketchy/smooth. If you are using adobe illustrator and you want smoother lines, you can use the pen tool to subtract points in a line (dunno if that is the help you were asking for)
can you tighten up the line art?
