Practicing some Profile basics

[DoublyDan]

So I have recently decided to LEARN some techniques instead of just reading about them. Yesterday I captured a few profiles and I would like some feedback...The second one had a fill light but I deepened the blacks to see just the rim effect.. The placement of the key light took some patience.
Key gridded with an 1/8 grid and the fill light was used with a lumiquest 3 softbox. The first image also has a bounce card behind the subject.

So what do ya think?

I chose not to use a hair light or a BG light intentionally, mainly because I don't have another couple of flashes (I may have been able to use some of my hotlights )

Thanks for looking.
