Hmmm
This may come off as inflammatory and way off base, but this is my personal opinion:
I don't take anything on deviantart seriously. I have this stereotype ingrained in my head that anyone on deviantart is sitting at home in their moms basement drawing unicorns, scanning them, photoshopping them, and putting them on deviantart hoping for some backslaps and virtual high-fives over how deviant their art is.
And this is how I feel about flickr as well.
If you really want to grow your photography, participate in the challenges here, or make posts with a few images asking for critiques.
Or better yet, post at photo.net, or POTN, or Fred Miranda.
PS: You have the most adorable dog I have ever seen!!!!
EDIT: I don't mean to disparage deviantart too much but as far as actually improving your work, I don't see the value in it. I have yet to see much real critique or criticism from deviantart users, but then again, I have not even checked it out in years. Maybe it's changed?
