The above image is a guide that I created to use tommorow in the Concept art lessons. I have created it using just lines as you can tell. No tone, but I did try to add sense depth using different brush sizes. The Plan for tommorow is:
Depth (using colour)
Atmoshere between the layers
I think I might be able to pull this off. On a side note the tablet I have doesn't seem to support 'pen pressure' so I will need to get one from Uni.
