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!
