Jybe, you're on the right track... Your letter structure looks decent.
Try this, separate the letters entirely from one another, they shouldn't just be attached all willy-nilly, the attachments come from the flow of the letters when you develop a style that you like.
For now, write out J Y B E just like that, make sure every letter is solid and flows well, separate of the other letters, it should be balanced, and solid. Take a piece of graph paper and make squares on it, then draw each letter inside the square. Once you're comfortable with that draw them overlapping but not attached, play around with which letters overlap and which do not, still simple letters and no attachments/extensions. See how the letters flow together, play with them, but don't let them connect...
Another exercise you might want to try is to write every letter, and see how the letters are built, the only way to understand letter construction is to draw every letter.
Also: Work on handstyles, they should be simple, the less strokes the better....
