If you're gonna post a sprite edit here, it may pay to at least post the original so for those of us not familiar with the sprite can identify the changes you made.
But yeah, this forum isn't big on sprite editing, myself personally; I don't mind if you need advice for some sprite edits you've made when you're still learning the basics. But, I don't speak for everyone, so I think it would be best to make original work.
how about this for an exercise, just turn this thing into something:
you could just AA the lines, or turn it into something really detailed, it may help you to start out with something not so cramped so you don't have to worry about cramming in detail while still maintaining readability.
so, good luck
