Nice work. I agree, the gate house needs a little less color saturation. The shadows are fine unless you are looking for perfection, in which case you need to somewhat match the shape of the shadow with the tower's roof's peak, also the alignment of the shadows is not the same on all the buildings. A couple are more south direction while most are southeast. I would not have noticed if you didn't ask, but I am not as particular as some people are with those details.
