Now I am wondering how fast a dragonfly takes off and flies away, and whether it would be hurt at all when he releases.



Also I think the you made the dragonfly too large, but you just might have larger dragonflies where you live, I don't know how large they get further south, or, if this is a fantasy picture, you can make dragonflies as large as you like.



Lastly some would criticize that in real life people do not hold the bow to their face for seconds while aiming and then release. With a war bow you draw and aim at the same time, and release almost instantly. There is no time for an insect to land on your arrow. But if this is hunting bow, the draw will be much lighter and you can take aim for a few seconds, long enough for a dragonfly to land on your arrow.
