I like @itsmeafterall suggestion of a bank of tall units along the back wall, eliminating the need for a tall unit in your window side. You could havefloir to ceiling, with oven unit, pantry, f/f and appliance garage.
Then rotate island as per my earlier suggestion.
Move your window down, personally i'd make them taller if you can , taller windows let more light in. And if possible I would avoid wall units, to me they make a place feel cramped, especially if you're short on space. You should have enough of you use the back of the island, you can even put shelves on the 'corridor' side of your island for cook books/nice crockery/vases etc.
If you put your dishwasher to the left of your sink and your crockery to the left of this it will make loading and unloading easy.
Yes to drawers, we have ikea ones and you can fit so much in. Nothing disappears till the back and is forgotten about l. We have internal drawers fitted too for things like spices, cutlery, chopping boards.
I would also consider where you're putting your kettle, personally I like it out of the way of the main work space. It allows people to make a drink without getting in your way.
And we have our recycling boxes hidden in a unit under the boiler. I got sick of stiff being left on the side waiting to go outside, so bought the bins from ikea. Work out where your bin will be. I'm thinking of altering under our sink, currently we have a pull out bin in a cupboard, but I prefer the ones in a drawer, so that's on my list of kitchen improvements.
