So this is definitely a lot better, and moving in the right direction. The main issue I'm seeing is that you've got way too many big curves, way too early in your construction. As shown here, you should be constructing things out with straight edges (drawn with a ruler to avoid all the extra sketchy lines you've got going). Only round things out at the end.

This is certainly still looking a lot better, and I am really quite pleased with the level of construction, but I do want to see you trying to keep things blockier. I'm going to assign one more construction, but this time forget about all the curves. Keep everything straight, and see how far you can take that construction.
