Crossword 8: Gesture indicating perfection

I intended to make crosswords more frequently, but I was traveling for a couple of weeks, and then it took me a while to get back into the habit.

This one is good but not great.

The good part is that I managed to fit a lot of 15-letter words into the puzzle.

The bad part is that in order to do that I had to use a lot of 3-letter words as fill. But most of them were not terrible 3-letter words.

Please enjoy!
