Since it was me that mentioned the painting first, and I didn't specified what I don't like, I leave my opinion.
The worst is the horse for me, the brown it's a little dull... a White horse would look terrific, with that contrast of red and gold.
The golds are nice yes, but I've seen better, and the leopard skin has a tiger colour - orange and white.
We're going paint it so, we must try to do better!
Steve just spoted the unmarried lance.... a problem one needs to fix.
Someone above mentioned the legs and the possibility of the figure bend with the wheight. Well, is hard to say for sure what may happen, but the tail is also on the ground, beeing another support and most certainly there is a rod from the base of the tail up to the horse body for sure (same as the Roaming Knight). The 3 "support pilars" might well be enough to make the wheight of the figure come down to them, and not bend.
