A great piece of work by you, everything about the image is to adore.
I'll begin with the background first as it is one of the most significant part of an image. The cloudy background adds a charismatic effect to the image and makes it more appealing to the eye. However, a few strands of the pale teal lines look too irregular and rough. Other than that, the background is a perfect match for the character.
The character [The girl] itself has been drawn to near perfection is looking very good. The Sky blue hair with that flabbergasted smile looks astounding with the color scheme and the outfit. The only thing I found somewhat disturbing was the fact that the hand coming forth was too big. It could have been drawn to more perfection, but overall a good job.
The bird, has a decent posture and the happy and innocent look is to adore, especially with those azure eyes and the golden look gives it that majestic feeling.
Overall a job well done, and I hope to see more of such works in the future.
