Hi @oresteg, you asked us to comment on this portrait:

Ramón Melendez's work is really very good. Beautiful portrait with such fine work on the features of face and to reflect emotion of the character.

Nice soft work on shading to create great values with pencil.

In Art community, we need to know who is presenting the Artwork, who is the author. The signature of the author is very important, I can barely read it on this photo.

Also we encourage to present the reference of Artworks if that was done based on it.

I will just leave a link to the Artist who perfectly presenting his work and giving reference:
