Your forms are looking pretty good, It's mostly color and shading i think you need to work on. Your shading tends to be purely on the outer edge of the obects, which makes them all look strange. If a surface facing a light source there should be more light on it than that. You have started to show a bit of improvement with this on the monkey's body and arm though. Just keep pushing it.

As for color, your color ramps are pretty dull, which is a problem a lot of folks have. Don't just shade with a darker/lighter version of the base color, also bring it more/less (depending on darker/lighter) towards a red/blue/green/purple, etc. Just a bit away from what you have as the base color. It'll add a lot more life into the pixel art. (for example, in my avatar the hair's shading doesnt just become darker red, its also more purple)


Also, the shadows on the monkey one are wrong. from the shading, the light source is coming from the left, but from the shadows it looks like its coming from directly above, and maybe a bit behind them. Keep consistency in mind :)
