I've got a couple of pieces of art that I will need to sell, but the following piece I can't seem to figure out the name of the painter. I've entered several guesses but haven't had a hit. The first image is the whole piece, but the second is a close-up of the signature. I'll take any and all guesses! Thanks!

(Sorry for the tilt, the painting's in a hallway so I can't get the camera far enough away for a proper shot.)
What IS this signature???
