This is an original and technically well done portrait. At first time it look like a sketch made with a small number of line with some graphic software, but when I see the portrait more in deep I understand the real power of this piece made with traditional technique. The lines so chaotic and full of movement ,and the drops of varnish that make an interesting base noise, give at the watcher a sense of confusion underlined by the flat black of the varnish on the white of the background. just an observation: the use of charcoal is unnecessary, it obscure the web of lines and don't add nothing at the composition, but this is a just a personal opinion based on my personal taste. P.S. I'm sorry if there are grammatical errors , my english is not good.
This is not one of your best pieces and I don’t think that it truly shows your potential, don’t get me wrong it is a fantastic piece of art but you have shown use greater art e.g. gestures, big bang in water colour. They are some of your best pieces and they show so much. This piece is so simple and common for you. It could be just me? Due to the fact that I am used to seeing such great work from you, that this just doesn’t do it from me. It is some what different to some of the recent stuff that you have been producing in colour and emotional terms.
