Thanks for your comments guys, at first, I was not sure about the concept, that was given to me, but at the and they really look more like a proper unit, more empirelike
classic french (and also Czech) tri colour is a nice contrast, and works very well for them I'd say...
I'm sorry that I couldn't spend a bit more time on them, but we agreed on a certain price and time (around 3 hours on each rider, including horse). It seems to be plenty, but after spending 18 hours on horses only, I've realized that I'm in deep trouble...
