Great work, especially on the Monsoon2D one!
I was kinda disappointed to see that I didn't get an equally successful treatment

Anyhoo, the style I was going for was Kenneth Fejer-esque newschool, and it was my first pixel after a decade, so it's maybe silly to call it my own style or to try to replicate some bad decisions I made, but what the hell.
It is my impression that you sacrificed the style for the likeness. You should keep the shapes more blocky and clean-cut. Take a look at Kenneth's work, every area of color is well defined.
Here is a quick edit. It now probably looks nothing like you, tho:

Hope this helps.
