Wheatley design update

I haven’t drawn my Wheatley in a while. To be honest, I’m not happy with his design. So I sat down this afternoon and tried to redesign him.
(For one thing, he's ginger now! Cause I could never quite figure out the right shade when he was blond.)

I’m happy with the newer style and outfit, but I can’t help but think that I’m subconsciously ripping off some other Wheatley. >__<
