whoaaaa random flurry of colors and way too bright. Stay away from putting random shapes in random places try to create some flow to your pieces. I'd hate to say this but, the color scheme is really bad. Choose a few colors that work well with each other. I think It's time you got introduced to another technique like smudging. As of right now, your skills are a bit limited. How's this tutorial? :

Don't let my criticism put you down, but rather take it as motivation to get better. My comment doesn't mean that you should stop making work when bored or whenever you just feel like it. Let your ideas run wild and create some unique art.
BTW, nice sig.
