Can somone please tell me what i can improve?
I think you could work on defining the outline of his wings a bit more using shadow and light, or creating a darker, thicker outline of his entire body. The bottom wing sort of blends in with his body, so you can't really see it. Overall, I think you colored him really nicely, and the pose is pretty cute, like he's being curious. ^^ His eyes are great, too! :)
I love your style of drawing Night Furies. :)You should work on your shading. ^^It's very awesome. :D
It's really good maybe try doing some really detailed sketches that's what I would really like to see
