Hey Ulco,
so you jumped the MD train too?
At a quick glance I see the following:
the large fold across is body above the belt is very deep and strong. Looks a little too much for me.
But the rest is ok, I presume?
The rider sits quite far back on the horses back. If he wants to kick his heels to direct the horse he will hit its rear legs.
At least that what it looks like to me from this angle.
Cool stuff, as always, though.
CHeers, Klaus
