As a task to learn and understand Adobe Illustrator, I decided to create illustrations and pictograms using just shapes, no pen tool or brushes. I also used the pathfinder tool to help create the shapes I need for my pictograms.
I really like the outcome of this task. I feel it didn't work so much for the fish illustration as I feel it doesn't have a flow to it like a fish should have, feels very round. I wouldn't like to use it as a finished piece. But the rest works really well. I feel my favourites are the single letters connected to each zodiac, they are simple and self explanatory.
