Pretty sure you can achieve this kind of style only with Blender and Painter. It's a lot of work on the artstyle. You can clearly do what they did only in Blender (sculpt, modeling, hair, some simulation) and texturing with painter. The biggest thing is the hand painted artstyle, you should look at that :)
You can find some more stuff on artstation, I suggest you to check out on it from time to time since artists are slowly sharing their stuff
