SINderella Rockafella

Studio lighting and being in the studio is something I haven't done much of, I know already I'm probably going to feel somewhat awkward in the studio. That said, its an area of my skills that I really want to get comfy with. 

Last week we did a studio shoot with the lovely model Emi aka SINderella Rockafella, and had a play about with lighting. 
The light setups were relatively simple and added to them as we went along. 
I really like some of the shots I got. But, I find it tricky to work out if I like them because its new to me ( I haven't really created images like that before and there is a little wow factor in there) and so they seem amazing or if they're actually any good. What do you think?
