Nicely done. Mister Samuel Jackson's eyes really popped there xD.
Yea, CSP has no "heal", so we mostly do things manually by copying, duplicating (there is a "copy brush"), blending, air erase, etc. Pretty much all exercices translate well to CSP though, and I don't think Marc even mentions the heal tool again.
Just to add, since you have a strong art background and foundation already, you might find term 0/1/2 exercices a bit simple since the course was designed for people starting from zero (basics of gestures, basics of perspective, spatial awareness, etc).
Still, try to stick to it as much as possible. Reaffirming those bases really helps, it includes some curious tips, and very soon you'll start looking at some very interesting topics (like mastering gradient maps, overall anatomy, 4/5 point perspective, some of these were new to me).
Cheers!
