As per your post, plot front is wider than the back side, which is called WAGH MOOKI plot as per Vastu. If you believe in Vastu, you must consult a Vastu expert for the layout.

upper floors 3 of ur bedroom's headboards are towards north. Not recommended due to magnetic pull. And two of bedroom toilet do not have ventilation. please look into it. Over all planning could be even more better if you refine it a bit.

There are no setbacks on the east and west so it would be unauthorised construction which I am sure you are aware of. You have tried to squeeze 3 bedrooms in a plot that could realistically only accomodate one bedroom. As a result there is inadequate natural light and ventilation for the central parts of the house and toilets. Nevertheless it would be better to avoid toilet in SW corner. Stairs could be east west orientation. Plinth to be atleast 45cm above the surrounding ground and the plot itself should be above the road.
