Thanks for your comments Michele and Leslie. I'll have to go back and resize the picture from my tiff file - when I resized the jpeg it got fuzzy, hence the pixelation around that eye (it doesn't look like that in real life!). I'll post a new one tonight when I have access to my original files.
Now that you've pointed it out, I agree that the background does seem too harsh. I confess I was in a hurry and didn't want to give it much thought - I'll have to rethink what would look best
