"frog-faced shroom monster"
well it reads like a guy with goggles wearing a cute hat, which can be likened to a mushroom cap "shroom" or with a green slime riding on his head, so frog faced doesn't really fit unless you had his actual face as a frog head, and "monster" he reads as a human, just letting you know
so not so much critiquing the art as your naming convention and logic, the piece itself doesn't look bad for the intended style, but I do notice the lighting is very banded and inconsistent, the 'cap' shows a more upper left style light source where as the body reads more frontal left side, the main issue being the highlight on the front right shorts leg (your left) being too bright
