Im working on it, unfortunately my brain is a seive... In the meantime, as I try to gather the different traits, at least I can just enjoy looking at them.
Thanks for the input, I'll look up Bluejays. The groups are separate, those on the right came with a load of other Japanese transitionals, the 3 on the left are from a mixed vintage lot, but there were a few vacors in it.
Brilliant, thanks for encouraging me to give it another go. After a bit of experimentation I settled on black background, in a glass of water. Feel like I've graduated in some way now that I've been fishing round with a wet hand, trying to get the best part of a swirl upright 😀
