James, your pipes look pretty good, seems like you have the basic ability! If you can't afford a class right now, time to hustle! In the meantime, I'd suggest looking at videos online and/or through smartflix (

one comment: that spiral wrap of clear you put on the stems might be a concern, it doesn't look like it's welded on good enough. Typically you want a smooth line with no undercut at the join.
