I did some drawings based on the 1st letters of each zodiac and created illustrations around the letters to match their zodiac sign.
This one below is based on Aries, and it's element is fire. I scanned into the computer and then traced it in Illustrator to create a pictogram.
I really like the out come of this, the colours of the fire against the black really stands out.
The one below is for Aquarius. I feel the drawing is better than the digital one. But I think they both work as a illustration.
