I think this is great! It has a nice lo-fi feel to it, and the style is consistent. Not everything has to be shiny and crisp and realistic. This reminds me, in a good way, of some of Mike Judge's work such as Beavis and Butthead and King of the Hill.

your pieces seem to often lack depth, not enough shadows/contrast and the "color correction" is off, considering different parts have a different strength in saturation. (i.e) hella blue pants)

Try putting some more time into the work, some more shading, detailing etc.
