Heeey...! I know your work...!
I've seen your sleepycast and batman animation.
Good to see you're doing art portal related stuff, too!
Overall there's a slightly .. unfinished(?) quality to this piece, which is why I think a 4 is appropriate, but it works well with the whole Halloween theme. You also mentioned that you're doing a drawing every day in the month of October, so it'd be unfair to expect you to submit completely finished/polished art every single day.
Hope your daily art challenge turns out well!!
It's a tough commitment!
Keep up the great animations.
