Lesson #10:

spacedude – sketch

spacedude – vector

Thought this one was OK so I tried a larger one as well:

Turned out this technique isn’t that hard to master, it just takes loads of time and patience (the monster took me bout 4 hours).
I hope to do some more of these in the near future.
Fortunately I still have loads of old sketches in my drawer so it’s straight of to the vector part
