Happy Halloween! time to paint

So here is my halloween, These are all done in photoshop and I tried to take 20-25 minutes on each, (some of the better ones are more like 35-40 mins) This is for an assignment due tuesday at 8 am, it's mostly just a value study but just for practice I took it maybe a half step further than that. I used the same brush butt adjusted the sizes and opacity. My favorite is Kennedy, he is just so Gosh darn Charismatic!
