Looks sorta nice but two things about it I don't like.
1. The hump on the spine ridge of the horse body. Wouldn't be there if it was a single mesh like the Zygote Centaur.
2. That Horse neck drape prop might help to tone down the appearance of the hump but what if you want to create the Centaur without draping or armor. The hump.
It is a solution but I can create the same solution See pic using the old P4 Horse and MilPT as Thorne's Lisha with custom morphs and misc armor and props attached. The seam was covered with a cottony veil or fur but it is only a last ditch effort. Creating the figure without drapes or that hip fur makes it less than nice.
