hmmm ... I think that the edges of most of the shapes are a bit rough, I don't know how to fix that I'm a camera boy ... But also I think it would look a lot cooler if you added a nice background like in this tutorial [link]
Hm pretty interesting.. It's always good to develope a new style rather than use the usual 3dsmax/c4d render mesh and some brush. Don't like this one so much, everything's not just matching. Anyway, keep going.
