That "unknown" character you're looking for on page 14 is a hella common kanji (風): こんな風に. And just like that, you now know the kanji for wind.
Edit: Just noticed someone else pointed out it earlier, so my bad for doubling on that. I won't add oil to the fire, but do your best on your next work if it ever happens, and do get tips from people experienced in the matter, feel free to hit me up if you want even, I'm always up to help new folks.
