This is a great pic! But to be honest, it has some flaws. For starters, the head of slendy in this pic is very oddly shaped, kind of deformed football-esque. Another flaw is that there are way too many tentacles on the pic. It wouldve looked better with less tentacles. And another flaw is that his legs are nowhere to be seen here. Its as if he is walking on his tentacles.You could have at least put his legs there. Despite these flaws, its a decent pic, but it couldve been better. However, its pretty creative. overall, I give it 6/10.
I like it. I think my favorite detail would be the way you drew the spidery hands. The placement of the symbol is kind of sloppy though. This piece could have done better without it. Otherwise, nice work
