Yet again, I find my inspiration in Sutiblr's photography. But then it became a mash-up of some reference photos I've had lying around. Both practice and substance.
You can see the original sketch in black lines, then the more structured image in red. I then cleaned up the lines and added some shadow guides.
If I am clinical about my process, I have to say my energetic sketches tend to have something... more to them. More real, less fuzzy... But that's me being self reflective about my work.
I hope I do justice to the shiny textures of fluffy pink rubber goodness.
