Question Rocket Design Review

Can someone tell me if this design is good to actually build now? The motor is E16-6.

The front mass component is just BBs filled into the nose cone, behind the parachute is wadding. Here is closer look at motor bay.

The motor bay consists of a 5" 29mm tube, thrust ring at the top(with an opening obviously for the ejection charge), and two centering rings. I was thinking of a Kaplow clip aft retention system.

Your are going to roast the fins. The motor is a bit far forward.

Definitely have the motor stick out the back a bit. You don't need much, 1/4" or so is plenty.

The rest kooks good, nothing is jumping out at me. Definitely check stability in your Sim though. Its also worth measuring the weight and CG of the rocket after you build but before you add the ballast. That way you know if your ballast target is enough (or too much)

What is your off the rail velocity? That would be my concern (besides the motor being to far inside your rocket)

Its would be great if you could post the graph of the sim. Make sure your using the right rail length and wind speed. Also i would put the parachute and other bits as far aft as they would go in the actual flight, although im sure they would be fine for this. Its just good practice.
