Shun me if this is already made, but I am allowed to express an opinion and in my opinion, I think the basic customization already in the game is a bit weak, and a tad on the sad side.
I believe wizards should be able to customize further in what their characters should look like. A change in the eye shape, eye colour, mouth, lip colour, ear size, nose, are all good and you know, minor things but they make your wizard literally yours, and that's what should matter most is being able to fully have control on how you want to look in the game!
An idea to extend to this one would to be to add a barber shop ingame to change your hair style or colour! I think that would be a fun feature, some hairstyles can only be available at a barber shop and could cost either some coins or crowns to purchase.
Hope you guys consider my idea, thank you for your time
