It's actually a little hard to tell the size of the hat in proportion to the head with the angles the photos were taken. But I will say that the hat color looks too red/orange.
Also, I would try and track down the full Hot Toys outfit--it really was the best thing about the HT figure and is a significant upgrade from the Sideshow outfit (of which I see you have the shirt as well as the jacket) in terms of both quality and fit. I think the HT pants are also a better fit than the ones that are on him now. Those new line boots should be fine.
Good luck!
