Peter, I am sure that they look a Lot Better in the Flesh, than they do in the Photographs.
Regrettably, all I could really see, apart from the Wild Life Backdrop, was the Reflected light that has drowned everything around it.
Could I suggest that you try using a Plain Light Background.
Take the Photographs outdoors during the Day, Out of the Direct Sunlight, with the Flash turned off. Try to get as close as you can while showing the Complete Pen, and load them on this Post.
I do look forward to seeing what you can do.
Regards,
Brian.
