C&C on portraits with softbox and umbrella

Here is a shot of my wife using a softbox and an umbrella. I had a 600EX-RTs in each.

Any and all C&C are very welcome.

The other photos were too big for DPR and so I have a Facebook link below if you would be kind enough to go and take a look.

I just got the softbox and have a lot to learn, but I think I like how the umbrella diffuses the light more. The soxtbox light seems to get too harsh too quickly and blue! It has 2 diffusion panels on it and I still have to power it down a lot. But when I do that, my photos are not as bright as I would like, and I like my photos a little dark to begin with!

I have the ProStudio Solutions EZ-Pro 32"x48" Softbox from Amazon. I thought it was a decent size to give decent soft light and not too cumbersome to move around on location.

Any help will be greatly appreciated.
