AWESOME! The ONLY thing sticking out for me is how wide open Harry's eyes are...maybe it's just your style, but I think that they should be narrowed, especially with his eyebrows that way, and in such a forceful motion like that, I can't imagine I'd have my eyes wide open!!! But I really like the colours and basically everything else.
Oh my god Salazar is terrifying. And really old. I think in reality he would be younger and incredibly handsome because he was the one who made the chamber and would want everyone who saw it to think he was absolutely amazing. But I like the drawing the way it is. It's really awesome.
