face

This is pretty tricky, but doable. The image has partial symmetry. From the clues you can work out which areas have symmetry and reflect them on themselves. But be careful, don't assume any symmetry outside that area; the face is not symmetrical overall.

A few more hints. You do have to make some assumptions about local and global symmetry based on how the puzzle appears. Don't be afraid to try something; if you end up stuck, you likely can move or flip some of the structures you've created. Also, if you are not sure how to proceed, sometimes you'll be able to use "meta-logic" along the lines of "If the item is here, then it becomes easy to solve; if the item is here then there's no way to go forward.".

Ummm...huh?

This was pretty simple to figure out. Only thing I wasn't sure of at first sight was the 6 dots of the nose. And even then I just flipped it to the second option in order to complete.

For those who want a clue and not a riddle: the puzzle has symmetry except for the nose (rows 8-11, columns 7-10), fives in r1 form eyebrows, r13-17 = mouth.
