I have always admired portraiture. I think that the Human body as a whole is hard to render, and I highly admire those artist who have done it so graciously. As means of improving my skills, I have being working on a few portraits experimenting with various techniques.
At times I find it difficult to render certain features such as the nose or the lips. Every person is different therefore every portrait requires it's own special attention to detail.
Over time I have improved my abilities and learned what works for me and what does not. I do not think I am as good as I want to be yet, but I'm pretty sure that with work and practice (lots of practice) one day I'll be there.
