I love your bear ....As you mentioned, I am not sure about the background either. Perhaps the grain of the frame and the grain of the background are distracting me...not sure. Maybe more of a lighter boring colored background. Here is a painting of a horse that I thought looked good with the background. If you had a bigger background, and since you airbrush very well, you could do a moon so that is what is lighting his fir like this picture I found on etsy but maybe you don't really want the silhouette look... Not sure if this helps. marie
