Your gallery definitely shows that you're going in the right direction!! 8D The only advice I ever stress to people is to work from reference whenever you can, even if it's just for practice and not a finished piece - working from photos or screencaps and things like that is a great way to explore anatomy and angles that you otherwise wouldn't have considered or known how to draw, Using other artists as reference gets tricky, because they have their own style and might be teaching you something that isn't "correct", but still well handled - but working from real people means you'll get a good foundation to then apply your own style on top of. Then you can break the rules whenever you want! Good luck!!!
Oh yeah. I just got the app "pose tool 3d" on my android tablet, its been so helpful. Male/female model that you can pose in literally any position. Perfect for anatomy or foreshortening. It was only 4 bucks or so, quite worth it.
