Draw This Again! - Sonic.exe

oh boy,, when was the last time i drew that monster?
uh,,, maybe 2014,, who knows honestly
but on the left is probably one of the oldest i could find from my old account shadowvampirefan (thanks to knowyourmeme/com)
and on the right, is me redrawing it but in my well,, better style i suppose
have i improved? you be the judge
