Not too bad. Try to lower the eyes a little bit. Do you use a template? If not you should, it will help you improve your skills.
Click. Just make that the top layer (so you can always see it), make it transparent-ish (65 works), and scale it up to whatever size the image you're working with is. Then, before you scale it down, delete that layer.
@LadyDEATH: We should have a tutorials Sticky. idk, just a suggestion.
