There's really no other way around your foreshortening problem but to find good reference photo for it... keep digging on the internet. Rotate your entire image to align the castle vertical, and check if it's possible for the knight to remain seated on his mount at that angle. Also look for reference image of horse rider or shampoo advertisement for that hair-billowing-behind-head look. At the moment the hair seem to be falling towards gravity that's off to the side.
