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.

Yes Ekta, Make sure you use a 12 mm toughened glass. It could be colored on one side or just over a wall paper. Make sure all the ends are properly closed. Thanks, Nitin CORNERSTONE DESIGNS Bangalore

Hi Nikita, The color scheme which you want to go with would definitely look good, only catch is the freshness of the colors. Try to select colors with fresh tinge that is avoid using any yellows with black tinge.

high full length shelves sort of block the view and create partion in the continous space. sink is too close to the shelf? fridge? believe me when you are working that close to a shelf it keeps on hitting a person's elbow. the shelf would become inaccessible to the person making food because it is so far away. try to demarcate between different work areas and how they would interact with each other. like spoons plates etc, near the half island or more accessible to the person using them. range too near the sink.
