I really like them! They are beautiful!
My only concerns (which you may have already thought about but just in case you didn't) would be the durability of the paint and the safety of the paint around horses.
I'm a stickler for making sure that whatever I'm using is safe for my horse. I wouldn't want to use the brush, have it get wet, get on my hands, and then indirectly feed some of the paint to my horse by accident. I'm really careful about that.
And also, you just want to make sure that the paint will hold up in any situation around horses. You know how messy things can get sometimes and how durability is a humongous part of this.
They are wonderful looking. Good job.
