To the OP, thank you for sharing your insights and suggestions.
Speaking freely, I'm not sure where I stand on this; on the one hand, I wouldn't wish to limit someone's enjoyment of the game and I agree with one of the posters above, I can't see the harm. We play these games to role play after all and that is inherently a unique perspective to us all. Personally I don't care for seeing my visual characteristics represented in the characters I make, other than their personalities but I appreciate that is just my own opinion and basically irrelevant.
On the other hand I'm a bit torn on the subject of elves. As far as I know, and I am happy to be corrected on this by the many people here with far more knowledge on the matter, that elves are generally portrayed as having ethereal features, in that they look really quite different from humans? And we are talking DnD elves here, so although they are inspired by myth and Tolkien, etc. it seems appropriate to use the DnD portrayal of Elves as reference?
In conclusion, it wouldn't really bother me other than from a purely 'traditional' sense, which again, is probably irrelevant.
To digress, if anything at the moment I find the Elven heads, particularly the male ones, far too human looking with chiselled jaws etc.
