No. They look pretty awful. The only exciting thing is OMG SPRITES CROSSOVERS OMG and that auto-turns on some kind of switch to make people think it is great.
They are badly done and not very professional looking and it's very obvious when you had to deal with this kind of stuff for several years. It looks fan made. It's not nitpicking at all. Nitpicking would be complaining that the sprites are not 16-bit (GBA sprites). Calling it nitpicking is turning a blind eye to bad graphic design.
