Hi Sharon,
You have such beautiful artwork/paintings! It's a shame they aren't being seen as often as they might.
I just did a quick search on one of your paintings that caught my attention... Large Mouth Bass:
I used "large mouth bass" as the keyword phrase and only 5 pages came up. Your painting wasn't included. I suspect it's because you don't have it in your keywords/tags. It's the title of your painting and I think it should be included in keywords. I did a search under paintings for "bass" which includes music, guitars, etc... so you can't rely on that one word in searches.
I did another search under paintings and title and there you were on the 1st page. But... you can't expect that someone will automatically know the title to your beautiful large mouth bass painting. I looked at your lion painting - gorgeous!!! Your keywords are severely lacking though.
I'd suggest you take a look at your keywords and add more... if only the title. Get a little creative and used "large mouth" "large mouth bass" etc, to get your images in more searches.
Hope this helps... beautiful paintings, Sharon! :)
