Gorgeous colours and a great drawing! I love the colours they bring a sense of happyness to the picture and gives the character an awesome feature ! I also like the idea of the force field when she is happy, this is drawn very well too
The only thing I would work on is your coloring in ( some untouched parts on the neak and muzzle) and work on the background ( the grass doesn't look quite right ) but im sure the main focus is Bambi.
Overall a wonderful piece of art and character design! Keep drawing!
