Yes, I do hear you Mike in regards to cropping. The are a few painting(s) such as the one you referred to which are hundreds of miles away in storage. Having had no plans to offer prints on a website when taking pictures of them-- I almost didn't include them -- and will maybe just remove them. I have already pushed the envelope a bit too far, cropping the edges until compromising the sharpness.
I agree with you and Marlene regarding the background. I thought about adding thin borders around the ones with white background but have been a bit hesitant on that idea.
Thanks for the input, Mike and Marlene. The bounceback of thoughts is greatly appreciated!
