The problem about Harry's particular talent is that rarely he got somebody in the book other then himself who rated his skill. And if there is, it is rarely someone with enough credibility.
Harry said he is good with Thaumaturgy but that is just his own opinion and it can be argued that he just think himself good in those area because he is been doing that for years. No particular gifted talent there.
If we say he is good with creating enchanted items: armored coat, energy rings etc, Well, in Death mask, when Susan ask him why he do not carry enchanted items like the rope he use to tie Susan, he said he is not good enough. At the same time, we find out in White knight that Ramirez, who approximately the same age as Harry in Death mask, perhaps even younger, can make a shield glove with the principle of entropy which probably is as good as any of Harry shield bracelet before White knight.
When he animated the T-rex in dead beat, he told Ramirez that is just hard work, not complicated. Again we can argue that it is just Harry being modest, but no one other then Ramirez compliment it, and Ramirez is just a young wizard with limited amount of magical muscle. He do not have enough expirience to rate that feet and due to his own limited amount of strength, he might think that Harry's feet in animating the T-rex is impressive because it is beyond his own strength.
If we say that his massive strength is a skill by itself, well, nothing to be argue there. That is only a matter of oppinion.
Other then Bob's comment in Proven Guilty about Harry having a gift creating things like 'Little Chicago, we do not have anyone with significant level of magical expirience compliment Harry on a particular magical feet.
