First of all, thanks Jon for the great class as always! 

Was very interesting to see the sticker making process!

Here is one of my favorite stickers from stickerapp.com

For my project, I decided to try and recreate the old inspirational/encouragement stickers that you used to get in school or something (great job! etc.), only a little more fun :) . 

Hope you like it!

here are some initial sketches:

Next was a revised version:

I then scanned them in, cleaned them up a little in Photoshop, and vectorized them in Illustrator.

Here is the final version..Thanks for checking it out!
