Most of the art isn't that bad. I think a different thumbnail would probably help give a better idea of this gallery. Even if it's not oldest to newest that way.
A lot of it has a sort of mid 2000's vibe to it, IMO, but that's not necessarily a bad thing. Just an observation of the shading, face shapes, eyes, etc.. It's higher resolution than most art from the mid-2000's, though.
