The little rough sketch of Rin asleep, leant on the wall and holding his sword, is adorable and wonderful :3 It is in fact very impressive that you've drawn this much even while you're struggling through your art block!
OH MY GODS YOU ARE MY FAVOURITE ARTIST EVER! Naruto and Bleach and Avatar and Blue Exorcist (yay for Rin Okumura!) and Harry Potter and Fairy Tail AND Fullmetal Alchemist (Edwin FTW! 12 episodes in and already shipping. Though I have been shipping it since like episode 6, so...). Also PJO, Soul Eater, Young Justice and the odd Disney though they're not in this sketch dump. Basically it's like everywhere I look I see amazing art of, like, 90% of my major fandoms staring back at me.
