Firstly, I am not the greatest fan of gts, nor an expert about this. But I can answer about what I wanted to see in a gts-themed video:

-Just the growing girl in front of the camera. I don't like watching boys or hearing them... it's a major turn off for me.
-Shoe ripping is ok. Why do always the cameramen forget that the models have feet?? It's frustrating when the camera is in an angle that shows the girl from the knees up.
-The girls should speak something. Or at least, let them try to act as "surprised" or "panicked" about the growing change.
-Yes, we all want the total destruction of clothes, but please, keep the hands out of sight. You can make it expending 0$ in FX (well, you just have to pay for the clothes, I mean).
-Hair growing? Perhaps, but it could be expensive if you want to create a decent effect. Long nails are ugly and unnecessary for me. You can live without these FXs.
-Nudity. I'd say yes. Nudity is needed if you want to add some credibility to your work. Buuut, if this is a major problem with your models, you should search adequate camera angles to show only some parts of their anatomy. It could be not so easy, but it is an interesting challenge, isn't it?

Lastly, sorry for my horrible english, and I hope this may help you anyway.

P.D.:As you see, I am more into growing process than in giantess women themselves.
