Tero,
welcome to the forum, please feel free to ask us anything you need to know. We are a friendly bunch and help where we can.
Comments by Les and John stand, but I'll add two things for your future turnings.
1. Don't always think you've got to turn a finished item. Just turning to understand the tool, or a technique is sometimes more important.
2. We've all done this and sometimes it's the hardest lesson to learn, but don't turn the biggest thing you can out of a piece of timber. The shape or design is more important than the size of the piece.
