@smurfmier1985, @csehz thanks guys! hopefully I will be able to finish.. At the moment I’m stuck in the middle part.

I came up with the solution of connecting the last edge in the end to where that part should end, added couple of edges using the knife tool and shape it a little bit.

Here is the result, a nice curve and now working on the details, hopefully this solution will work if not start from scratch that part again.
So far, besides learning the tools and how the edges flow and how affects the mesh I also learnt that a 3D model is like programming, a model is like a big problem that has to be broken in small problems then solve each little problem to resolve the whole thing. That is the approach im using.
