Made variations of posters that I made for my boss.
My Boss really wanted people to GTFO.
Important points
1. Be confident and bold: take a leap of faith. It's really all about your journey. So get excited! Your work will show your passion in the end.
2. Look and look again.: OBSERVE OBSERVE OBSERVE! [I think that's what Linley meant by this] Go outside and observe. If you don't get outside much, *cough* like me *cough*, then pictures will work, for now. The world is your oyster [I like oysters], it's time for you to explore!
3. Be pleased with your progress. : Keep all your sketchbooks and date each drawing. When you get discouraged, look back at your other drawings. I'm pretty certain, you'll see that you've come a long way.
