Looks like you have several things to consider in the layout. What the view out the window ? Do you really want to see more of whats outside? Cooking is always best on the outside wall to get it vented, island cooking is a last resort, downdraft dont work well at all and the island hood is typically obstructive. Looks like the wall should come out to open the space up. Best advice is to have a designer come to your home and see it in person. There are costs associated with every change and it is very difficult to judge just from photos.The design phase is the most important part of any kitchen remodel the builder is only going to install it as the plans layout. Find a great designer that makes house calls :)

I love sky blue and want to paint my room, so i think it depends upon choice and likeness

That is a really small space,I think maybe an apartment size sofa would help you get the look you need and a smaller table or even removing the table and using two bar stools

after watching my daughter and her husband agonize over the way their expensive timber floor has not held up well after 3 years, I would recommend tiles/wood look tiles with under heating. Their beautiful warm expensive floor looks like it always needs a clean and polish, not from neglect, they have cared for it well. One of the boards now has a slight and painful moan when it's stepped on :-( I grew up in a completely wood floor home and although it looked wonderful, my Mother hated it. ....and the mats ! Wood is a lot harder to maintain than tiles ,(no matter what the die hards say) the modern wood finishes are much better than they used to be.... But a piece of wood is rather arty no matter what it's used for and it does demand to be loved and cared for.....and if something goes wrong it's a lot more expensive to fix than sand and cement. Ultimately you have to be happy. BTW underheating tiles is warmer than timber :-)
