Elves and Half-Elves ears seem too extreme for Faerun elves.
Elven facial bone-structure seems too human (that said, I've seen attempts to make elves look less human and it often comes out badly...so really low priority here.)
Trinkets - Some little detail to the character creation that should be there regardless of outfit....a tabard, a necklace, a shoulderbag, etc.
Tieflings should have the options for human-ish ears and possibly wings (not flight, just wings), also it would be nice to have broken horns or shorn wings as options. Hornless IS an option, so how about a case for each of the existing horn styles where the left or right horn (or both) is ragged and broken.
Scars in general.
Piercings
A lot of warlock marks can be accomplished with tattoos, clicking All Skin Colors or All Eye Colors, but there's probably a handful of other options.
Heterochromia...also, eye-scars...etc
Separate Moon-Elves and Sun-Elves....honestly, this is less about character creation than it is about dialogue...you can approximate the look of either with existing options, but Moon Elves and Sun Elves have vastly different reactions to the world and different reputations. Moon Elves tend to be more egalitarian and live among other races...a lot....Silverymoon Moon Elves and Humans are practically the same culture. Sun Elves.....tend to be the haughty types you expect when you hear "high elf" and tend to treat other people (including other elves) with disdain.

For options not yet in the game and hopes for options to be added:
Half-orcs .... is it too much to ask for the range to be like Shadowrun orcs which can range from "attractive human with tusks" all the way to more traditional takes on half-orc.
Gith - make Githyanki a subrace of Gith and add Githzerai....the Githzerai as just as much invested in Mind Flayer hate as the Githyanki are
Draconic sorcrerer - scaling options for appearance - ranging from light to severe.
