I recognize the background from Marvel VS Capcom, a game with a 384x224 resolution that's stretched to a 4:3 aspect ratio (making it practically 384x288 if the tall pixels were squares instead).
Did you draw the character with ratio-corrected pixels before stretching them back to squares?
The bear would be really slim and have a bit of an egg head if she was actually in a CPS-2 game.
Sometimes when somebody attempts a Capcom arcade-style look for their pixel art, they try to draw the characters wide, because they've seen the Capcom sprites before. But often times, they don't take into account of the fact that old Capcom games from the 90s were never wide-screen to begin with, but they make the assumption anyway based on the resolution, even if square pixels weren't a thing until flat TVs became popular enough.
