I think this is very well executed and balanced - I too would like to see a warm-tone version. I am curious as to how you got the border, as it suggests cyanotype/self-coated paper but I don't normally see such detail/tones in those types of prints.
This print is a Ziatype, which is a kind of hand coated palladium print. It requires no developer. Depending on the formulation it can produce a range of tones from cool to very warm. The Ziatype process is well known for smooth silky tones. Because this was made from an 8 x 10 original camera negative it is even smoother and more detailed than might otherwise be the case.
