HI there, Yes, our site can't upload renderings unless they are jpgs or png, so i have converted them for you..

I'd put in a tile backsplash. Stick with a solid color tile so your bottles won't get visually lost. Solid color doesn't have to be boring, look for interesting shapes or textures, and play around with different colors of grout to make a statement. The one in your picture looks very similar to the 2nd picture below.

You could go for tiles with design if they are simple ones. if you want plain, you can add some life in the country style with an exposed brick facade or subway tiles. for colours, it depends on how far out of your comfort zone you're willing to go. white is the safe choice, but you can go for blue, green, yellow, all pastel hues

Hi Nikhil... u can fix back painted glass as per your color n choice n fix on existing tile . if Budget is the concern, u can apply film on the tile .
