How would you define a "portrait". (Patreon)

One of you patrons has asked me in a private message for: "... some (just) portraits of Martina". 

I wonder if this picture could qualify as such, because for me it is really difficult to cut out her beautiful breast from any picture. 

But I understand his request: even if all of us are inevitably driven to the secret album and the hot contents concerning this girl, the real magic of Martina is in her eyes and the constant enigmatic smile to turn pale even the Monna Lisa.

If this is not "portrait" enough, please let me know, I will be happy to try again, and again, and again...
