Bingo!

That's (in my opinion) a large dividing line between amateurs and those who are more "intermediate" as photogs...realizing that things need to be lit and then getting 'er done.

And next......A five in one reflector.

I know almost nothing about flash. I am not a flash user except for one thing. Fill Flash. That is it. You got it. Now I love this photo as I am strangely attracted to pregnant women.

I do wonder if the shot could be a tiny bit better, and really I am only speaking tiny, if you would have had her do the jaw line trick of pushing her head outward a little. I don't think on this person it would make much difference but since seeing that video I am consumed with the jawline.

Good job Chelie!

Very nice! 

I'm assuming that on the non-flash shot, your flash had not fully recharged, and so you got a shot without?

I have been in situations like that, and sometimes, it's really nice to see the flash version and the non-flash version to compare just like yours above.

In one situation, I realized that NOT using the flash was better.  I was shooting a jazz club with really sh*tty lighting.  My flash batteries started to die, and I forgot my replacements.

I really couldn't tell any advantage to not using flash with the LCD.  But when I got home, I started processing.  I was happily surprised to see that non-flash photos were better in that situation!  My ISO's were skyrocketing, but I took them into Black and White, and the grainy qualities looked fine.
