Are these arts the official depiction of elves in FR? I am not belittling the quality of these art in any way, but I don’t think it’s a good idea to change the look of an entire race due to the good art of non-white elf on the internet.
Currently in BG3 I can make an orange skinned, green haired elf with all black eyes.
Yes, if you turn off customization restrictions. By the way, sun elves have bronze skin, while forest elves have copper and tanned skin. And I still don't see the point in introducing new faces for non-white elves. You can make a black-skin elf anyway.
