I know, it pretty much sucks. But that's why I drew it in a sketchbook and not on something expensive or important. It wasn't meant to be viewed by the general public. I was just getting my feet wet, and artwork like this was very new to me (see my fine art portfolio here).
The Rots have grown up since then (a lot), and in celebration of their fifth birthday I decided to paint Rodney as I thought he might look today (see below). Rodney was the very first Rot (he's in the upper left corner of the sketchbook page above), and he's changed a bit, hopefully for the better.
Over the past few weeks I've posted some photos of Rodney as I was painting him, so you can scroll down to see in-progress images or click here to see all the updates on the same page.
