Lisa,
Don't be discouraged. Sometimes it takes a bit before people get around to commenting. Sometimes they just get missed.
I have a painting in the Unveilings section from September of 2004 titled Mike and Deb (little advertising on my part there) that I'm still waiting for responses on.
For what my opinion is worth, and I am a beginner, I think your painting looks very photographic so, if that is the look you are shooting for, then I believe you were successful.
Good luck with the valid opinions.
