A copy after Rembrandt's Jeremiah Lamenting the Destruction of Jerusalem, this was done as part of the OFD Workshop in the anatomy forums over on CGTalk. This is the original painting: [link]

It proved to be a huge learning experience not only in the techniques of Rembrandt, but in creating textures in photoshop with something other than a normal round brush and the subtleties of light, dark and edges. It was a very worthwhile exercise, and I've already put techniques learned to good practice in other pieces, I would highly recommend it. If you want to improve on your anatomy or figure drawing in general, as well as partake in workshops like this, you must come and join in the Anatomy forums over on CGTalk! You'll find them here: [link]
And as some people seem to have this daft notion that CGTalk is only for super amazing digital artists, the anatomy forums accept work in all mediums and of all levels of talent. If you've noticed an improvement in my work over the past year, a lot of it is due to the amazing support and community in those forums. I can't recommend them enough.

This was all done in Photoshop CS2, exclusively with the default chalk texture brush at varying sizes, without pressure.
