Well you’re a true craftsman. My first one was really similar to that, also a banana lol but looks decent enough on a mantle even tho it’s not playable. I tried my hand at an angled headstock once, and it didn’t pan out. I use one solid piece for the neck and I join another shorter length of wood with with 45 cut on the bottom for a heel. Some screws, a little wood glue and a whole lot of sanding to round the edges, and it doesn’t look half bad, for an amateur like myself.
