Those pendants are great! Nice job.
You might as well get some blow tubes and start practicing using those as well. It will teach you to do nice even welds.
Also, you need to taper the mouthpiece down more and open the carb up. The carb needs to be bigger or the same size as the mouth, otherwise it will always pull through the bowl and never clear. Make sense? When you start a piece, shape the mouth piece first thing, that way when you come back and pull it off, you only have to clean it and it is already the right size and shape. If it still ends up to big, heat a little back from the hole and use a marker/paddle to work it down to a good size.
Good job sticking to the clear/fume, and you still get color play with the pendants. You are learning how to work various colors without wasteful results, and sticking with clear for pipes gives you a great foundation. All colors move and behave differently. If you play with color on pipes while learning, I think it takes longer to get a good understanding of how the glass moves.
