I love the electric glow radiated by the image. The glowing blues did a good job with making them the center of attention, however once my eyes are at the center of the piece, it just feels too empty. I like how you managed to use the blue glow (I love stuff that gives off a glowy ambiance), however feel that you could have added something to make the center feel less "hollow," such as a small protrusion from the c4d.
Still, it's pretty cool and a while before I'll be able to get close to the results I see you having. I can't wait to see more!
Thanks and I know that the emptiness as you put it wasn't a great design choice. In retrospect I'd have liked to have a third part of the render zoom in towards the camera/right hand side, but oh well.
