Definitely true - if you continue to practice, you will get better! Welcome to 2draw, blah blah, etc, and so on. You used your background colors nicely, I like it. :] But if I can offer a word of advice - if at all possible, try to avoid using the fill/paint bucket tool. It tends to result in those icky white spaces you can see around all your lineart. Layers can be a big help with smooth coloring; if you don't know how layers work, check out the forums, and we would be glad to help you out. :)
