This is fantastic; such a vibrant piece - full of movement and suggested form.
As trendy as it is to like someone's old stuff better than their new; I'm finding myself more and more impressed with the quality of your work as a whole. It's growing into quite the epic body of abstract art!
What I'd really love to see is for you to push yourself in other areas; working to new media for example or new aspects of those you already produce for. For example, most of your artwork is designed for a desktop wallpaper or poster print; why not billboards, commercial posters or magazine spreads. Form follows function, perhaps it's time to exercise yours a little more? I don't know, perhaps you already do those kind of creative projects - if so, I'd love to see the results.
I think pushing yourself into less decorative, more functional arenas of design would be great for you both creatively and in terms of your freelancing career. Diversify that portfolio mister!
Quite nice. I think the thing that most bothers me about this image is the way everything just seems lumped into view. It's all very central. The alignment of everything is nice enough, it provides a strong impression. The warmth and variation of colours works well, and the sparing use of single pixel lines is a nice touch... just seems to balance everything.
