For those who remember, I had several options for the nose of the model to get the nose of the model as round as possible.
I decided to try only 2 options that I had.
In the end I chose option number 1.
YOAV
I took advantage of the fact that the nose is divided into black and white in four places, so option number 1 with the slots around the part was preferable for me, option number 2 with the petals, a method I do not really like.
I took the part on my palm, wet it a little, and with a round tool at the end, I rounded it round until I got a beautiful round dome.
Then I closed the slots with glue and paste it to the nose of the model.
I present you a short video for illustration

Final result .... Round shaped dome.
