Here's some images of the process I went through working on this original character called Seignik. It's a bit jumbled.
I drew this concept at GDC 2010. I used a Sharpie marker for the line art and Faber Castell markers for coloring. At the time, I just drew this character for fun with no future modeling intentions in mind.
When school started up again I had a goal to practice as much modeling as I could outside of schoolwork. The character I drew during GDC was one idea that came to mind so I created this very rough turnaround sheet. I wasn't worried about rendering anything here - I just wanted to quickly get a sketch done so I could get straight into modeling.
Here are some WIP shots I recorded last year of the modeling process:
