That’s cool -I like the background too. The smoke seems to be an after thought - post processing - not really part of scene, if you were looking for constructive criticism.

Thank you for your comment, the smoke has been rendered with opengl, but the simulation scene smoke with you the final scene, not renderowałem her cycles only with preview opengl and it took much less time if I had to do it by rendering it in cycles, I just wanted to smoke a little:) thank you more times for your kind words.
