Welcome to GG! Hope you find the forum to be all you want it to be.
First thing to know is that Deviant Arts doesn't allow hotlinking. Yeah, I know YOU can see the images that you posted in your message, but the rest of us can't without getting the URL from the properties and then pasting it into a browser so that we can look at that URL directly instead of having GG's host do it for us.
The cure is to do one of two things....
1. Upload the files you want to share to your GG portfolio. They'll be small since you're a free member, but they'll be visible in your portfolio and you can link to them from a message. Of course, you can upgrade your membership and be able to load larger, higher resolution images.
2. Find yourself a web hosting or picture hosting site. There are lots available... some cost a small amount per month (go check out PHOTOGSERVER.COM for one I can recommend - others will have other recommendations - for about $4.00/month you get a whole lotta space (basically unlimited) and a whole lotta bandwidth (again, basically unlimited) and some pretty good customer/tech service)... OR... you might already have some space with your ISP (can't tell who you're with since you posted a hotmail.com free account as your email address). For example, my ISP is charter.net (the cable folks) and I get a 20 megabyte web space automatically and at no extra charge. That space hosts my images since I don't use it for a personal web space. I host my commercial account on PHOTOGSERVER.COM since I can't do commercial on my charter account according to the TOS.
As far as your two images go... looks like you nailed the exposure on them.. got good dark blacks, details in her hair, and good whites with lotsa grey inbetween. What you might have done, though, was bounce more of the light off the wall so as to provide a bit more fill on her... I find it works best, unless you're going for the dramatic, to keep the fill within a stop or so of the main.
A little reflector or even a piece of foam core would kick a little bit of light back in as well.
Of course, if you're going for the dramatic....
Again, Paul... welcome to GG!
