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 DOS elves and lizzards.
This is just an announcement trailer, i think. But yes, humanizing of Fantasy races' appearance is a problem, that will ruin the big part of Fantasy World atmosphere. Divinity game series was never about different nations of human race, scattered in all corners of the world. It is a Fantasy world with completely different races, not only in their appearance, but in their lifestyles, history and cultures. So yes, humanizing the appearance of the Fantasy races should be completely avoided, their unique features should be emphasized.
I'm for continuation of DOS2 concepts with improved visuals. A better faces and long hairstyles for Elves, tall and thin with a great affinity to nature and the skills to control it. And better beards for Dwarves - should be long beards, such as Tolkien's or Warhammer Fantasy dwarves. "Beards in belts!"
I think, all the problems with BG3 "Salad" or lack of adequate customization for fantasy races(such as elves or dwarves) was caused by Wizards of the Coast, who owns the rights of DnD. And this also affected ActIII in BG3, it is very compressed i would say. But the new game Divinity is Larian's project only, Previous Divinity games have been impressive, as Divine Divinity, Dragon Commander, DOS, DOS2. Thus, we have all the chances to see the right "Successor" to all the ideas of the Divinity game series.
