Thank you for such a nice appreciation, you're absolutely right, the jewel is the focal point as it is a great source of illumination, I love when you notice these little things.
Of course there will be more combinations of the inktober themes, the next illustration I'm doing comes with "Chop", "Prickly", "Stretch" and "Thunder", I hope it looks as good as the idea in my head. :3
I'm looking forward too it :)
