Hello Alex. That is a great shot of a monster creature. Or was it small?
What equipment did you use? Sorry if you have mentioned this elsewhere, but it can sometimes be hard to locate earlier posts.
On a more general topic, here is a very nice web site with some lovely information about reversed lenses. His images IMO are outstanding, and what's more, he uses relatively simple equipment (probably the same as Alex?):

I like his simple diffuser for use with a reversed lens. It looks easily carried about in a camera ruck sack too.
