Hello dude. And welcome. This place is more addictive than really good porn. Cuz here you never cum, you just keep eye-jerking on for ever

Anyway.. a little tip I learned when I did graffiti back in the days is that we almost mess up a little part here and there in a piece, so always try to cover up and hide the errors. A decent shadow can sometimes for example hide a wobbly outline.

Also try to have a light source.. exmpl. Upper right corner, drop shadow lower left.

Keep it up!!!
