Aside from sounding more like a cover by a beginner instead of a guitarist as talented as Yngwie is (or was), the production does it no favors either. The tempo just sounds off, the drums are weak, and overall everything just sounds kinda flat. Maybe it sounds better on the actual CD as I know sometimes Youtube streams aren't the best quality wise but I don't really care enough to ever make the comparison.
Also he can drown his vocals in as many effects as he wants but he can't hide the fact that he is certainly NOT a singer.
