Mmkay! My Humble Sprite-Shack

[Lexou Duck]

in the second image, the girl on the right and guy underneath dont carry the no-outline style very well imo
either try and use aa to smoothen things out or use selout it doesn't look too good at the moment

for the ike, maybe try and find a way to show a little more eyebrow ? looks great though

in the NES remasters, the mario looks pretty bland and doesn't add much to the original in terms of posing and design
samus' pose doesn't make much sense either, specifically in the legs

that greaser kid has something really weird going on the his right/our left side of his face, like you tried to show the sideburns and a little of the ear but it doesn't work
a clear outline'll look much better

and the before-last image, his look direction makes no sense like a chameleon kinda

all in all this is good stuff though keep it up
