I'm going to deeply apologize if it turns out I'm wrong about this but to me this just feels weirdly fake on some level.
I feel reminded of the guy who posted tons of concept art in a thread on adventure treff until it turned out he just took other people's artwork and presented it as his own, which also explained the pretty wild variety in drawing style.
This seems to be original work though (except where it clearly isn't) so who knows. But creating this much coherent content in such a short time is almost impossible in my mind.
Again, sorry if I'm wrong, and I'll gladly change my mind about this.
(I do find mixing resolutions like that very ugly though, and I'm not going to apologize for saying that

)
