Learning to use my flash - Harriet

Well, I have to try and figure out how to make the best use of my new piece of photographic gear - a speedlite 430 ex rt ii so here are my attempts at trying ETTL flash bounced from the ceiling and from a reflector held or propped in different positions relative to the model on camera left. 

This is also a good opportunity to introduce Harriet or Hatty, my patient model. 
Here she is  shot in natural, available light only

This is the easy bit .... She is about 2m away from the background - my lounge wall which is mostly quite dark (as in facebrick fireplace and a very large bronze picture above the fireplace. There is natural light on camera right, with french doors about 2m away providing a reasonable amount of ambient light
