split the segment on the right so youll have 2 segments close to the same length for the actual top hat. Then, Id say split em again and smooth em from there.
Right away the top handles arent right. But theres probably a lot going wrong that needs work. By a lot, i just mean a few factors. Not horribly wrong.
its still quite uneven. before you smooth, unsplit the sections back into 2, and center it as perfectly as possible. your apex is slightly too far to the right. then split it back up and smooth.
I only wanted you to split the segment on the left once, and the one on the right till you had a similar length. Then, smooth it. Then you could split again and further.
If you want, you could send to my email and Ill show you what I mean.
