Just a bit of a update.
I should have posted this on the weekend. I've been swamped.
But here's what I done for the next part of the elements. On my list to do is highlights, colour and then putting the two elements together in a piece and background to tie it all together. I'll be writing a more thorough step by step. wish I had more time to go through everything now.

Mid tones

Darker tones

The next is highlights and colours
