I started with a really crappy sketch. My intent from the beginning was to concentrate on the inking of the piece. Which is why I didn't spend much time on the sketch. However, the sketch is probably the most import part as it sets you up for the rest of your image. The better the sketch the better the end result.
After the sketch I did the line work. Everything is flat as the lines are the same thickness throughout.
Once I had finished the line work I began to block in the shadows and add spots of pure black.
Not quite finished, but I began to add details muscle lines and enhance the shadows. I still need to do the shell and his left arm is not quite done. I was thinking about adding color but I have yet to decide. The more work I put into it the better it looks but it will only look as good as what I started with. The sketch is very important. I gotta keep that in mind for next time.
