Unfinished Practice 1

So I've been trying to teach myself different techniques using photoshop and wacom since I've never had any proper schooling on either >.< I really like the paint/airbrush soft look I've seen other artists use in their digital art, so I'm playing with different brush types and opacities till I find the look I am going for....if you have any tips or suggestions please let me know, I appreciate any feedback! ^ ^
