The first thing I see is in the 3rd column from the right. The biggest number in that row is 4, so the space between the 3 black squares and the single black cannot also be black so it gets an X. The groups directly above and below that X must each be a 3 or a 4, so you can mark the next 2 white squares down as black.
That should at least get you moving.
