Edit other's skins is is the same as for a mortarnaab to start play liero v1.0.
You're trying to improve,by editing other's skins,to earn more skills,to learn make own skins.
It's pretty hard to make your ''own'' skin nowadays,as there's already great skins,and you want your skin to be great as them.So then,you could try to edit it.
I think Vux has done some nice edits.But the funny thing is that Mr. Slime is done ''correctly''(with colour changes and such) but Crazy Snail isn't.That is the only thing I'd blame.
Else,nice edits,keep some more edits up,and you'll be able to do your own skins!
Then you could look at your signature aswell.
