It looks good but how you gonna sink it? I've been making some out of pvc pipe. I stick 5 sticks of 3/4" pvc in a bucket of concrete, drill holes randomly in the pipe and stick 1/4" irrigation tubing tubing about 3' long trough the holes. Then I take two pieces of the larger irrigation tubing and shove down into the end of the pvc. I'll see if I can post a pic.
