I finally finished :') It's really hard for me to draw realistically because I haven't practiced that style yet, so sorry for using my 'cute' style, but I didn't want this to look like trash XD I was gonna give the characters some scars but like can sea creatures even get scars??? idk, but feel free to change how they look or their personality, I was feeling a bit burnt out at the end so the last one isn't the best but I tried. The first creature is an Axolotl, Axolotls can regrow limbs when they're hurt so that's cool, the second one is a Chomodoris Willanis and it's a Nudibranch, other than that I don't know much about the species, just that it looks cool. The third I kinda butchered but whatever, It's a Glaucus Antlanticus and it can use the poison of it's prey to sting predators, the sting feels very painful and has severely hurt many humans, even though it's so small.
