I see the bottom hinge needing adjustmant. I think if you looosened the bolts for the bottom hinge (to the door) and pushed the door inward 1/8" there the gap would be a lot less.
The problem is you'll also need to re-adjust the bottom of the fenders or the door may catch the back of the fender (worst case) or best case the misalignment will be at the door fender interface.
Getting the door to close perfectly can be tedious. Just remember to make small adjustments, then re-evaluate, adjust a little more, check again. I usually remove the striker catch and get it all adjusted, then re-install the striker and adjust that for best close.
