Look pretty good to me but I am no expert. I would however say that doing real joints is a better way to practice than just running beads on a sheet. It is actually quite hard to do an even width and spaced run on a sheet where doing a proper joint is easier, or at least for me it is.
Yeah I know didn't have much cut up and on limited time just trying to get a feel for it also not sure what is the most comfortable way to hold the tourch like a pencil or just on the handle
