Mark - exactly! - those where my thoughts too. I will try and make a combination of crossection and simple geometry and still try to keep it from interfering to much with the foreground parts. I could use more specified lighting to dim the background parts. Thanks for the input!
Beckie - Another good observation, thanks! Also that link shows a good scale relationship. I think my guesses where quite accurate but it’s good to have it comfirmed 
Sabie - well, I’m usually quite lazy too. But recently I’ve discovered, that the more I know about the underlying functions the more I can bring in a project at an early stage (leading to more fun for me when doing the work!) It has already proven useful, Mondays lecture was on the cell and its functions and yesterday I got an assignment of making some illustrations covering exactly that! It felt soo good to be able to understand the topic right away and to be able to suggest possible visual solutions 
Yes, please go didding in your old files - it’s really interesting to see how others solve things!
As for the animation, Our Lolo has made such a good one - I’m sure I will be heavily inspired by that when deciding on the storyline. :love:
Nathan - thank you! I’ve tried a slightly different approach for the texturing here, using visible brush strokes for both coloring and normal mapping. I think it works quite well and perhaps I make it less subtle for the next update.
Busy with other stuff today but always happy for your visits here, have a great day!
