It looks good to me but I would angor the ends as far from the edges as you can.
Yeah, I'll do that. I didn't mean to make it look like it's right on the edge in the picture.
I believe I would want the end in natural dirt, not built up excess dirt.
Ideally, yes, but I don't think I have another option. The 2 separate banks are so dissimilar. I have to build one of them up. We'll be sure to compact them.
