Positive Negativity

Normal sudoku rules apply. Ying Yang: shade some cells so that all shaded and unshaded cells form 2 form orthogonally connected areas such that no 2x2 area is entirely shaded or unshaded, and all the digits values in the shaded area are negative values. Killer Cages: VALUES in cages add up to the total in the corner. Arrows: VALUES along an arrows path add up to the VALUE in the circle. Kropki Dots: consecutive VALUES between 2 cells are indicated by a white dot, not all dots are given.
