@baukepost My english is far from perfect as well, we got lost in translation 😀 So a picture is always worth a thousand word, I’ll try to make myself understood:

– “add holding components to the rear part of the cover frame” is the red circle: for the moment you have it floating, I thought you could already add connection to the rest of the vehicle body, as you did in the front (blue circle). That way all the components seems to blend in with each other, and your vehicle will have more flow.
– “the “what-would-be-the-fuel-tank-if-this-was-a-motorcylcle” could be elaborated a just a tiny bit more: more curve perhaps ?” is the orange circle. The arrow points to a face that look very flat. I admit that in the reference it’s also kind of flat, but maybe think about giving it more curves. Below is an fuel tank of an “old-school” motorcycle, I tried to show you with the arrows what kind of curvature you can think about if you want to also give more flow to your vehicle.
