Hi,
thank you very much for the advice. I tried both, it somehow works for me (at lest for bow and stem), but the foot … I was not successful there. So probably I will see if I can mix this with the path (and get the quick result). At the end, I like to keep all the whites within the glass and so their gradients, but remove the reflection and the “outer” background.
Your result is very impressive. My final result should be something like this (ok this is one of the final results).

Thank you one more time.
