I've taken a few technical drawing classes and let me tell you it is no piece of cake! I found this artist James Gulliver Hancock who has some pretty sick technical drawing skills. These are only three of his map drawings I found (although his other artwork is FANTASTIC! I highly recommend checking out his website:-) which are all done by hand. There is literally anything and everything imaginable included on these things! I'm always inspired do to something when I come across pieces like this...like finding a local drawing workshop for me to brush up on my artistic abilities!
Definitely something to get me sketching again...A possible fashion line in my future??? Who knows!
Keep it Golden.
