@WeirdOwl I have similar glasses that I have made for her and they are slightly curved I think it is not that big deal, but I made ear like 30-40% bigger in final piece and I guess it looks better, thanks!
@chiara.arcidiaco oh Chiara, thank you so much, it means a lot because it was exactly what I wanted to convey with this portrait </ 3 she is like combination of Bulma and Futaba from Persona 5 in my universe
