Well, after watching the teaser, I must say that if you keep the tone of the transformation like that (kind of "TF arousal"), you will get lots of fans here.
Unfortunately, it is not my case, as I am more into "body horror", that is, transformations as painful and terrorizing experiences, like in horror movies.
Anyway, I hope you will be lucky with the experience. The model is superb and talented and I am sure that you will do a good work with the FX
