birds are just lazy M shapes that are in various stages of unfolding. Hell, they can be V shaped even~ Great hand btw~ That is extremely well-done. You're doing digital drawings correct? The cleanliness seems to denote such.
The character is drawn well be does need a bit more meat to their body. Granted, they could just be a scrawny foe and I'm nit-picking. You've got nice shading and it looks like you're off to a great start.
Also, when drawing landscapes, the foreground is darkest, while the background is lightest due to the distance. Adding a slight foreground object and perhaps some pale far off mountains would give a bit more depth to the last panel
oh, and I will suggest possibly using a font for text. I do like the hand drawn approach, but for legibility you may want to merely type it in.
