The background is also pretty good.

thank you, and yes, I think you're right about the planet. I still didn't find a suitable texture for the planet, I will try to make it better next time.

thanks :D

I especially like the lower part. The planet in the center looks more like a tunnel because of the way it is shaded.

Very impressed with this limit palette! It's awesome!

thx for your input m(_ _)m, after reading the rule of thirds, I just get mindblown D: I didn't realize about it yet, really appreciate it.

It is too bad your scene composition is really symetric and this makes it borring. Next to that colors and textures are very nice, but the final image could have been so much better.

Next time try to use the rule of thirds: http://en.wikipedia.org/wiki/Rule_of_thirds
