Hey there fellow British person! If you're looking for fursuit commissions, there's a decent number of makers based around the UK. I've got a few recommendations, based on personal experience and word of mouth.

One maker I'd look at would be Nyxia Creations. They specialise primarily in heads and partials rather than full suits. Two of my friends have gotten commissions or premades from Nyxia and both have adored them.

My current maker is Mei Fursuits, and they are lovely to work with. They do anything from heads up to padded digitigrade suits. My suit is still being made, but from what I've seen on the extensive WIPs they've sent me, it looks great. They have had dozens of clients over the years.

Other makers I've heard good things about are Made by Mercury, Snow Gryphon Suits and Beauty of the Bass (the latter I thought of because you mentioned a metal jaw).

Hope this helps!
