Slowly gradually taking on animalistic traits would be great, and having the transformation come in specific parts would also be really cool. For example having them also react to each part/phase, describing what they see (since we can't see it) and feel. Would also be awesome if the animal sounds would merge into their human speech slowly, if that even works with the subject. Like with a donkey...they might go 'what's heehaawww-pening' if the suggestion of braying is implanted strongly enough maybe.
Maybe you use some of the suggestions/requests in here.
(Oh and personally I'd love to see a hypnosis session into a donkeygirl or piggirl. Arguably more a mix than having them think they're changing into a full animal itself)
In any case: interesting work.
I like it. And you have our thanks for the work you've done so far
