What I see there is a glossy paint reflection that looks, from bottom to top, like:
1. grey-black
2. grey
3. blue
4. yellow/orange line
5. back to blue
I have difficulties understanding exactly what it's reflecting myself, but the gear and pitot seem reflected and should be included. I'd start by simply re-creating these colour "slabs" on the profile and then playing with them to improve the effect. HTH.
