A cryptic cipher

Insert comment about how this is true of every puzzle ever.

Did you try this one as well? Or have come across the technique? What did/do you think?
I like it as a pretty secure cipher with a simple method, that can be embelished in many ways.

I think it's a brilliant cipher. Just a shame I'm not a brilliant decipherer. I've never heard of it before - which, considering the amount of research I did for that puzzle with all the animals in, is surprising!
