Agreed with OP, elves appearance needs some additional work in overall. Some heads should be moved from elves to half-elves (mongolian and african for sure), some other heads should be moved from half-elves to elves. Halsin needs either appearance rework, either change of race to half-elf.
And this thread should be moved to suggestions and feedback section. It's quite important feedback, cause now elves are just humans with pointy ears and that's sad.
