I would suggest putting a splash back in, firstly for ease of cleaning behind the stove top. Secondly for aesthetics. Looking at the joinery around the fridge it is very much a focal point, to create a sense of balance why not add a darker splash back. Something that may work would be to look at a dark mirrored finish, which would add bling and tie in the light fitting (check to see whether it is rated to accommodate heat from stove) or even adding stainless steel. Another thing that could work would be stainless steel tiles, or glass tiles that have a metallic finish, or even a glass splash back with a metallic finish. As geometrics are in, you could also look at using perhaps hexagonal tiles with a few different tones, one being a dark grey and create a feature. With the addition of the dark tile it will tie in the dark joinery. Lastly freshen the space up with some bright accessories, it's easy to create or recreate a space with on trend coloured accessories.

Oh wow! It's so light and airy and inviting.. I loved those doors and was thinking why did you remove it but with the after photos I'm stunned.. It looks really good.. Something to be definitely proud of :)

Is this your forever home? If it isn't just take into consideration that coloured kitchens do affect resale compared to neutral kitchens that people can add their own pops of colour to with accessories. Blue kitchens do seem to be having their 5 minutes of fame but like any colour will date. I would go for the deepest navy blue - the bottom sample would be the closest but something even deeper would be better. Just my opinion though.

Wow, it looks gorgeous and the layout looks a lot more thought out. especially the rangehood and cooktop area. The appliance garage is a definite improvement as it clears away the clutter and makes everything look cleaner. Very impressive overall and well done.
