The question was universal, thank you for the thoughtful and detailed answer. :) I heard a lot of good things from Blender and a lot of my favourite creators use it. Might have to learn it for my own game in the future as well.
I think that's pretty normal and part of the process of designing a character, not every idea works and they need refinement.
That's a lot of characters you have in mind, will this be your life's work? Haha
Which is interesting since the elf is the most conventional fantasy race in the game so far, you can only escalate things from there I guess. :D
