Thanks for taking the time to reply and critique @Kevin-Longueil. Really appreciate your feed back.
I know what you mean about the background. I've since viewed the image on my phone and can see it's much darker compared to my computer screen.
That's a good point about the dwarf's pose. In my initial sketches I'd had him finding gold and holding it up to the light. The eggs read better than the gold but I kept the pose. Your pose does work much better.
Thank you for doing the paint over. It has really helped me to visualise your points.
