Hi Grzegorz - it is magnificent!!
I remove the scalp!
Show please this bust on a support.
It is a difficult composition, it is necessary to make a support beautifully.
Hi Ducz, I long looked at your beautiful bust and drew geometry your bust - look at my sketch - probably you will agree to add a small part for a torso and a hand? It not an error, only my small sight for your bust.
Yours faithfully.
