Hello Owen, and welcome to the AWGB forum. You show a remarkable degree of confidence in your tool handling for one so young. As you progress through this craft, you will discover many new techniques which will help you to achieve finer shapes and better finishes. What is important for now, is that you clearly enjoy what you are doing.
I was wondering.....are you near enough to a woodturning club to be able to visit them regularly? They have much to offer and I'm sure that you'd benefit from attending one.
Keep at it, Owen, you obviously have the basic skills.
