Now let's try some pixel art for a change...

[Crappy Blue Luigi]

you, uh
only added one more shade

it's still plain
also the feet just seem to be two ovals that are beside the "bottom" area.
iirc the goomba has "half-circles" for feet, not ovals.

Not really.
Though they're not exactly full ovals.
