The concept for this illustration is actually inspired from reality. I was traveling through Tyrol, Austria and saw a collection of cacti on someone's porch and they were all planted in large coffee mugs! All colorful and fun. It stuck with me so I decided to do an illustration of it.
You can get this design on a t-shirt from Amazon: http://go.shr.lc/2BEISKD
Or stickers, coffee mugs and other prints from my shop on Redbubble! http://go.shr.lc/2BHj9S2
The before and after shot. The image on the left is the original scanned drawing, the one on the right is after I vectorized it and edited it in Illustrator.
