    Looks great! Easy just like I said, now you are ready to build a composite airplane!
    Nice job, I think you will be pleased with the finished product the way you are going.

    The conformability of the cloth is called "drapeability", the ability to assume compound curvature of a shape with minimal wrinkling. One of the most drapeable forms of e-glass is 7781 woven cloth and perhaps that's what you used.
    It's a standard form, approx 10 mils thick and a 0/90 deg weave. It has high conformance and can almost be draped around a sphere.
    The cuts made in fabric to allow more conformance are called darts and used by tailors in fabricating clothes.
    I think your part looks fine.
