If I was trying to weld with a hammer, I might feel my skills were poor too, until I realized I was using the wrong tool.
Find/make/use more appropriate wire, and your skills will improve!
Yeah that top one...that will bring less attention to the straight part, though it may just be so visible now due to the tape. You can hide everything straight with folaige eventually.
When you get tight strong wire on there, you can grab a couple / / of wire with a pliers and put really tight bends in.
I think you'll be able to leave this till some sets, and still have enough pliability in the straight section to bend it next year, so if you smash the apex down, remember to account for how you will bend that other section. It doesn't have to look perfect now!
I was very delighted to scroll to the last pic last time, I thought you may have bought it, pruned it and just thrown the rock in at first!
So seeing the work, poor or not, was nice!
