So...this is a new character, Robin.
And a switch to a new style.
I personally like the one on the right better, because while drawing that one, it felt a bit more natural, and it isn't as drastic of a change from my original style, just the nose, lips, and eyes have changed.

I do really like how I drew the jaw and the cheek on the left one though, along with the cartoony grin.

So what do you guys think?
