I have seen this image before but like I mentioned, if you look closely, those elves are still human-like. The difference are the pointy ears, slight eye shape and size, and their face is a bit more angular but at the end of the day, they are still human-like. The OP mention they didn't like that the elves look human with pointy ears. Shadowheart is a half elf so it makes sense for her to look more human. Astarion is a full elf but he's a vampire, maybe they could of made him look more different but the problem is that he a romanceable companion and so they also want to make him look appealing.
I'm pretty sure nobody wants them to look monstruous or ugly, just less relatable while still beautiful and that touch of strangeness to them that makes them seem not caucasic, nor african, nor asian, nor anything but elves.
When it comes to elves not looking similar to real world races that is more of a personal choice but what about people of those races that may want to be an elf that represents them? That's also a personal choice. This would be up to Larian and WOTC and they can make the elves look like what you want but still tweak it represent those races.
