Intersting start, only real problem I suppose is the lack of consistancy in reguards to Harry and what he can do. I can't imaigne super world travler harry surviving all the ancient ruins and isolated villages if he acted liek this. He could got away millions of times but he lingered behind for no reason when multiple magical means were available to him, not the least of which should been an emergency escape portkey.
Then we have him get so angry over a destroyed rune (which he should been able stop the monkey begin with) he lashes out blindly, dropsh is wand and destroys a backup.. then just ignores his surroundings to get clubbed in back the head.
Pick a Harry, either he's knowledgable and strong, or dumb and stupid don't shift it to fit your needs other wise it looks really dumb when he has complete lapses of all common sense.
