FUE transplanted hair doesn't match my native hairline. Does this look normal? (Photos)

It may or may not look "right" but at this point it is too late.  It's been done.  You would need to wait to see what the results may look like in 6 to 12 months.  If you trusted your doctor with your surgery, you need to trust your doctor if your doctor says "not to worry". 

Even if it looks odd now I would give it a chance to grow out- it wouldn't be a good idea to get another surgery at this point anyways. Perhaps when all your hair grows out those spots will be covered, which could be what your physician is planning? Either way you'll just have to take their word for the time being- it will never be 'too late' to get another transplant.

Framing
the face with the right type of hair and utilizing the layering when needed are
the arts that a hair transplant surgeon should have in order to create the most
natural results. For your first transplant your doctor was likely just framing
your face and re-enforcing your hairline/temples.  You need to ask him the questions about his
long term planning. Of course you also need to give it more time.  As the transplanted hair grows out you will
comb in back thereby covering the area with where you did not receive
transplanted hair.  If you undergo a
second transplant the donor hair will likely be blended in between your
existing hair in the front for a smoother transition as you go back.

yes you are wright. İt is obviously seen that your transplanted hair doesn't match or blend with native hair leaving a gap. you need a revision surgery for that bald spot 5-6 months after that surgery .

The hair in the recipient area is most likely miniaturized and therefore will not match the donor hair from the back of the head which is more your natural hair

Since it is taken from your own hair it should match.  It is too early to tell, you need to wait until all the hairs have a chance to grow in to tell if there is any difference which may take up to a year.
