Okay, sorry. I was an asshole. The idea though is that pretty much any colors will look good if your shapes are appealing. Even the color scheme that you picked for your art would look good, had you been more experienced. Color theory really is all about mimicking effects of nature (rainy streets, misty jungles, skin-tones, etc), and much less on palettes and color harmonies. For straight up coloring tutorials and painting workflows, those are available right on youtube, but none of those will help you if you don't know the fundamentals of drawing and rendering. Drawing + rendering is what creates appeal, mood, composition, and story.
So draw draw draw draw draw draw, and don't worry about colors for now.
But if you really want to learn colors now, the bottom of this page (http://androidarts.com/art_tut.htm
) tells you how to do studies in both line drawing and painting.
