the same scout, but with colors.

Looking at your pictures, the only thing that makes them look 'anime' to me is the way that you are using an idiosyncratic shape for the characters' eyes. Try to avoid rendering the outline of a person's eye as a perfect 'dimante' shape, and remember that the eye yas a 3-dimensional quality to it that will effect the shape of its outline. This is more a matter of realism and, to a degree, style.

There is something that gives your characters' eyes an unnerving quality. By making the whole of the iris/pupil area visible, you make your characters look stunned and horrified- I've attached a photo of human eyes to give you an idea of what I am talking about. Unless a person's eyes are wide open in shock, the iris should not be totally visible, and should be partly covered by the eyelid.

Your noses could use a little work, but noses are an enormous pain to draw in general, and I think you're off on the right track. You've got a good grasp of the different head shapes of the game's characters, and looking at all of the different reference shots that people have put in /Resources/ should help you.
