Nice character design. Good posing and inking. I like the expressions, especially the one where she's turning her head. Good flow on the hair there. Just to let you know, though, deviantART doesn't allow hotlinking, so your picture is showing up as a broken graphic icon in the post itself.
As for whether or not you should use her one this site, I think that has about zero to do with her looks and everything to do with who she is as a character. What sort of character is she? What's her history? Would she fit into a fantasy setting such as the overall one used here? Those are some of the things you may need to consider and how that will affect how she plays out here. Hope that helped ^.^
