Thank you Stan Joanie and Logun7! Yes, it's been a while! I've been so busy admining on other sites! I'll try and stop by every once in a while. Good to be back!
The minimalist groove is cool and the colours are rich even though faint. The tube inside tube effect is interesting and engaging. I'd zoom out a bit and re-render without that top edge cutting of the tubes, unless of course just there everything gets all complex and the mood changes.
