A little bit of educated guessing needed at the end...but after only about 3 or 4 tries, I got it! Nice and mostly logical puzzle with a great pic at the end! Thanks! ~:)
Beautiful picture, you do need to guess the ear & to finish the face but if you use a sort of symmetry you'll get it first time. On the left there is a line down the face the same as the line down the right side, but the right side is all shaded so it is not perfect symmetry. Ues temporaries for the end & you'll get it :) Thanks for the drawing.
Lovely result. The last few squares required temporaries. Thank you Navan for posting the note about the line on the left side of the face being symmetrical to the line on the right.
