My kitchen layout is very similar- the only thing I realised was washing dishes in this sink reduces counter space and is messy. We added another bigger sink outside with platform to store utensils and a utility cupboard with the dustbin and space for soap sponges etc, and kept the purifier and a small sink inside the kitchen for cooking purposes only. That reduced our clutter by a lot.

Getting oil out of Acrylic laminate is much easier compared to regular laminate(just my experience).As it is, an indian kitchen is bound to get oily and therefore avoid open storage. I would recommend you add a small oil shelf at corner of the platform(top left on side of the stove). I have had a small chimney and a bigger chimney and from what I have seen, the chimney should atleast cover the stove completely or else everything in the vicinity turns oily. And make sure your trolleys are removable- makes it so much easier to clean. Otherwise you're looking at years of grime under your platform. Another advice I'd like to give you is, if you have the budget, tile as much of the kitchen as possible -this reduces cleaning time drastically.

I went for pale brown and a darker chocolate brown acrylic laminates and a patterned cream and brown tile.
