Trailer raises some concern in regards to racial identity. Elfs do not look as alien as in dos 2 and seem more like humans with ears. Lizards look less like chameleon-like type with prolonged necks and more humanoid. Concerning, but not critical.
I think this is sadly because of people are demanding conventional attractive romanceable characters and player characters ( as is already the case here, someone even made a whole thread about it) and elves are the most popular alongside humans.
The characters in the trailer look more like humans with little extras to. I do hope, that the trailer doesn't show the final look, but was a quick draft, because I actually like the alien look of DIS elves and lizzards.
