As a beginner, I certainly wouldn't try modeling every little detail on something this complex. Like Neox said, you can always break down complex structures like this into simpler shapes to make it easier. What I would do is build relatively simple geometry, and just convey the tiny details in the texture. If you're…
You've got your curves defined better here, but this looks nothing like the concept, and the geometry you have here still has a lot of problems, like "melting" at the bottom there.
whoops, the correct way is to use enough geo like this so the sides of the cylinder can be used as supporting edges like this or you can just use n-gons. It's not noticeable.
