Wings of Fire: Seawing Character Studies

So I am finishing reading book 2 again and I decided to do some character design practice with the Seawings in this book. I picked some of the characters people don't draw as often, like Gill and Shark and Piranah. Yea i know Turtle and Anemone aren't here, I couldn't fit EVERY Seawing on one page

I think I like Shark and Nautilus's designs the most, Seawing faces are still hard for me to get right, the canon art for them show that they have very narrow snouts
