My thoughts is we shouldn’t jump the gun based on leaked concept art that might change in the future and wait for it to officially come out and then give it a chance. If it’s good, that’s great. If not, we still have G4.
 
As for the concept art itself, I actually like it. Unfortunately most of the G5 speculation fanart is only from one specific type of concept art even though in the leaks each of the Mane 6 had multiple different concept designs, each in a different style.

Too gaudy
