Adjust the geometry so it curves with the hood. Make cuts where needed to get it to bend right.
Extrude the green edges downwards and adjust vertices to shape the handle.
On the underside of the hanle, extrude twice and merge vertices at the tip.
At the tip of the handle, extrude the two polys on the underside downwards to create the polys shown in red. You will probably have to smooth the hood to be able to get the handle to sit on the surface right. Put symmetry and meshsmooth modifiers on it.
