That was one tough project for a "first bow". Even tough for an advanced bowyer. I'm not surprised it broke in the fade. Others have expressed their concerns about the handle fades, and for good reason. I'm sorry your bow broke, but I think you've learned a lot from it!
Start a new bow, a more simple one. Get the basics of shaping and tillering first, before you consider a difficult design such as a Holmegard or Mollegabet (as this one is called). Just a simple flatbow.
