I've scanned some work in, from my other subjects:

 

 Tonal Studies, created using a range of B pencils. 

 This one is slightly different, as it was created using a sawing machine, it is not finished yet but is a good starting point for some digital art work.

 A simple stick and ink study of a fish.

 This crab has been created using pastels, it took me a fair few hours to draw, and it's still not finished.

Another stick and ink study, this time it is a crab.
