Not the way I would have done it.
To late now but that roof never should have been built that close to the sill, makes it far harder to seal and causes splash back on the window.
I would have installed the siding using a starter strip not J channel.
The J is forming a mini gutter and forsing all the water to run to the most likly area to leak.
Way to many exposed nails with what looks like no sealer on top of them.
