Here's another board for the "Kindle" story. This one I've done as a two-step sequence, so I present it in a comic page layout.
I'd gauge this 'un as being 70% done. I still want to bevel / detail out the triangluar doors so that more light can get reflected or caught. The upper version of this winged Imp needs more detail. The left wing in the lower panel needs work too.
What else would you suggest?
