>>1879635There are a number of issues. For the hat, you have some odd aliasing between the yellow and red. If you have to colors stacked on top of each other, the color below will peek through. Hide the coloring underneath to avoid that. For a couple areas of the hair, try to curve the tips more to give the hair more direction. For the bear eyes, make one with the circle tool, and copy it over to the other eye so they stay consistent. For the stars, use the star tool, and copy it to the others to keep consistency. For the X mark, use the rectangle tool, and copy it to the others to keep consistency. The rest of the small errors are a number of color peeking areas, or lines going over the edge. Use a high contrasting background to help spot these errors better.
Both your fingers and legs suffer from noodle finger/leg. You remove a lot of articulation from both areas, causing a very bland and boring shape. For the fingers, go back and make sure to show more bending at the knuckles and folds, and make sure you show emphasis of the nails from the original. This will make the tips look less flat then you currently have them. For the legs, show the knees bending more. It is okay for the knee to be more abrupt. You want to show the kneecap protruding out, as it is more accurate to real life.
