I also find the background very distracting, It's pretty but takes away from the photos. I have found that most photography prints shop keep a cohesive look by using the same style overlay/colors to their photos. If you do decide to keep it, I would mute out the background a bit more so it is not so saturated against your photo.
Your photography is lovely, I would hate to see your items looked over in a search result due to being hard to see.
I have also noticed you tend to repeat key words over and over, for example your Ford Truck Print. You use the word "photography or photograph" a lot. You could use other key words like "rustic" "home decor" "teal and gold" etc...
I love the way you demonstrate sizes! Your packaging is also very nice, how much does it cost per piece to package each print in a box with tissue and a card? Does it cut into profit? Does it help set you apart from other shops?
Just throwing some questions out there, some suggestions, and wish you the best of luck!
