Not bad, but honestly getting a bit dense with lines. I'd advice starting using different line thicknesses... thicker lines to outline the entire shape and then ones a little thinner to outline parts that are spaced out from each other or completely different parts, then the thinnest lines for the details

Okay , thanks~

So what, outline the large main sections with thick lines, then subsections with thinner lines , and details with thinner ones still?

Right, because atm, all the lines are thick lines and it's a little confusing to look at ^.^' so just get smaller from there.
