Have I gone to far?  Yes, I have the copyrights to do it but should I still do it?

See my most recent image “More then Human” for an example.

to some extent they should know beforehand, but in saying that, u have all this technology at your fingertips, why not make her a redhead with blue eyes and pale skin and then change some of her facial features a little....? and i think if u give the model a normal print, before u turn her into a monster, i think she should be happy enough.
if u are only experimenting then there is nothing to stop u, moral or legal, the problem might come along if she is still recognisable and u want to publish the images......you would need a release to do so, which will entirely depend on how nice you are to her when u ask for it 
obviously the thing to do is get one signed on shoot day, and make sure it says (and she knows) that there is a chance she will be morphed or have some of her human qualitys exchanged.

Hey some of us rather like it and in fact actively seek out this kind of work.
Living out the fantasy of being childhood scary monsters and myths is an awful lot of fun and to me at least far more of a giggle than more "normal" modelling

I personally have no problem with it (see my icon).  However you might want to ask the models you are morphing if you do want to post it on any site or forum.  Some models might be intriqued by what you do and some might be very uptight and offended by it.  You never know.
