After messing with the Character Creation for what was probably hours, trying to figure out what combinations I liked I would say my biggest complaint is the lack of diversity in the faces. I'm looking mostly at the Elf/Half-elf race because I love them and I can't get enough of making them in BG3 or in DnD. They're a race that I connect with a lot, especially half/elf since I'm mixed, and I would just like to see myself reflected in the faces. The Elf faces all have primarily Caucasian features. There is maybe one preset face that has eyes similar to mine but other than that, my character looks White. This isn't a complaint about those presets existing though, I really just long to see an addition faces that look more Asian like my own and I'm sure other Players of Color would like to see a face like theirs on an Elf/Half-elf. Like a one other person above me said, I think the Character Creator in Final Fantasy XIV is a great reference to look at for a Creator that offers a sweet middle when it comes to customization. I would be content if Character Creation went more along the lines choosing a preset and then fine tuning my character by being given the option to swap and change certain features.
All in all, I would like to see the Character Creator branch out into having a more diverse amount of presets/options for Elves. POC got angular faces too!
