I would not mix LED and CFL they have different looks and LED s are much cheaper to run. You can find a fixture you like and switch out most with LEDs, we have been slowly changing all of our halogen lighting to LEDs now that the LEDs come in higher wattages. We have 70 halogen lights in our house so I am doing 12 at a time, love the change. I like the fact that you can have a lot more lights off the same circuit too.

Colour...objects of interest...lighting...all add "energy' or we refer to as "movement" in a space. Interesting pieces of furniture with different textures and different "eye-levels". For instance, you can purchase 3 or 4 different forms of seating options...you are in India so you should be able to find FABULOUS furnishings for great prices. You could purchase a low-slung sofa, an extra large "floor pillow" (it would act as a chair or foot stool), a leather-covered round ottoman and an interesting crate/box with a slab of glass or intricate wood over top...this is your seating arrangement for the living room and will work as a great "hang-out" space that you can enjoy by yourself or with a tonne of people hanging around! With all that visual "movement" from one object to another to another, you will create interest! And "interest" is energy! But your best bet for energy...people!

I think a comfortable distance between the island and the counter is around 42". It seems that you have only 30" between your cook top and the counter. I might be a little too tight. The wall between the entrance and the kitchen could be 4' long instead of 6', you would then be able to move the island a foot which would give you more room between the cook top and the island. Could you switch the location of the toilet and vanity in your dad's bathroom so your enter facing a vanity instead of a toilet which is a lot nicer.

In that space you will only really have room for some seating and a DR table and chairs I would be looking fo a long low shallow unit for the media pieces and hang the T.V. on the wall 10.5 ' is very narrow. The room in these pics is almost exactly the same size as yours , if you see where the empty fireplace is that is where I would put your T.V. and then wap the bench for the sofa .
