There is a chance that you are familiar with the character that you can see on screen. If you are familiar with the character and you are happy with the thought that you can have this right at your very own desktop, you know that you need not worry about anything. The gray colored background just looks great with the character that seems to be looking at you with sharp eyes. No need to feel scared of the character though especially if you are familiar with her. If you are not, then you might be simply happy with the way that this character looks like. This will be up to you.
