DEUT has a much stronger explosion if you manually set the LIFE to 65535. I.e. console !set LIFE DEUT 65535, or the same with the PROP tool. You may use a smaller number, but it will be truncated to 65535 when you upload your save. Any smaller number, and the explosion will not be maximal.
Gotta work on the staging. Otherwise not bad.
However, I would suggest removing the clone ir changing it to a Breakable clone so it is more realistic.
The excessive fireworks is causing the fuselage to burst and break. I recommend decreasing either their numbers or spreading it out. I would recommend to get rid of a little firework even if you spread it out.
