Thanks for your feedback and the AA-tip

Thanks with the rim suggestion! Then it would pop more, I did not thought about that.

Maybe double post next time to have it still in my gallery.

Thanks for the feedback! Also thank you for the explanation with the value, I got a little bit blind (or nevertheless did not see it because of *beginner-eyes* :D).

Yes, the bottom one is filled to the neck :) Maybe, I give it a try in isometric perspective or jump right to next exercise.

Thank you for your feedback! Partly the difference is a subtle change in shading (less saturation, etc.) or a reduction of diameter of the surface.

Thank you very much for the kind words! :)
