From what I can see from the angle of the picture, I agree on the QH/paint look of him -- most likely there is some TB in him back someplace(s) in his pedigree (as is true of an awful lot of that sort of horse these days), but quite possibly not in the last generation or two.
Playing 'guess the breeding' from a photo is never a very reliable business, though.
Just enjoy him
Have fun,
Pat
