Edit: Ah, I was hoping you were going to showcase some siiiick new strats to off the Proto Crimson Head. Looks like you made it out of the battle by the skin of your teeth!
The Proto can be pretty unforgiving. Try and make sure you've got a handful of shotty shells handy and don't allow him to get up close and all handsy with you. Mind you, if this was your first playthrough, don't worry - the Proto makes short work of most players on their first tour.
