They do have a certain creepiness to them, but probably not an intended one. Of the bunch, the Wendigo is my favorite. Yours apparently prefers to huddle near a fire, despite a decent coat of fur to keep it warm. Gives it a more humanized impression which adds to the scare factor.
MS Paint for many people is difficult to use. It's archaic in comparison to newer, better programs, including other free ones, which I can't figure out for the life of me. It's probably why I will use if I do anything digital at all. I lost my stylus at some point though, so I ain't going digital until I can afford to buy a new one for my cheap tablet. I oughta show you one of my MSP doodles at some point.
