Here, I reworked it a bunch and reduced the colors a bit to be more cartoony.
Notable changes includethe cockpit and the tailfin, the former of which should be a bubble in the front and the latter of which was changed to include room for the directional rotor. I also added an air intake, stripe, and the rotors, because it was easy and why not.
There's other improvements that can be made here, this was just a quick thing I did, but hopefully it helps.
