I can never draw enough birch treessss, the texture of it and rain :] used photoshop and paint tool sai ( for more questions / answers go to F.A.Q )
p.s. the little dark-ish ones are not exactly totoros, they are more like forest creatures ( or spririts ). definitely inspired by Totoro!
Haha, I agree, birch trees and rain are always very enjoyable to draw. It looks like you had a lot of fun painting them here, as the entire picture has this wonderful lighthearted and uplifting tone. Thank you for sharing this delightful little scene with everyone!
