Keep going! unless that right side runs out to the edge id so keep it moving unless it cracks with some visual displacement. And if shes destined to blow keep tillering nice and slow and watch the thing explode on the tiller tree. Youll get a nice adrenaline rush and learn a lot once it fractures out and you can see splintering and where the bow gave up and that varying thicknesses at play that lend to failure as well as how cracks like that act for you in the future.
If you do feel like failure is imminent on the tiller tree take it off, its not actually that fun when the now nunchuk bow decides which direction to bounce
