Pretty much every name is taken, unless there is one you have seen local to you I wouldn't worry about it too much.

 

Aspiring toy here, is Guizou taken by anyone? I didn’t think it was but I just wanted to double check.

 

Probably somewhere, but don't worry about that. Just do your thing. Personally that letter combo would not work out for me but that's just me. Doesn't me you can't rock it

 

How many hours would you ideally spend a day to get good I heard 3 hours is the gold standard depending on your aptitude thoughts ?

 

I'm not sure if there is necessarily any golden number, and it depends on the person, but the more practice the better I would say. Letter studies can be a big help too. Doesn't necessarily have to be a piece a day or anything. Just sketch and keep going.
