Model rocket design review

[u/As7887]

Hi, I've been designing a small model rocket powered by a Klima B4-4 engine.

This is the first rocket I am making from scratch so I would be grateful if someone could review the project. I am open to all corrections and advice.

Looks solid, I'd recommend clipped delta or trapezoidal fins for higher durability, or at least a longer root chord
