Feedback on a spacecraft model

Hey. I’m currently modelling a spacecraft for a project of mine and I want some feedback/improvements:

Some parts are a bit shitty like around the fins since Ive added vertices that dont connect properly but those I will sort out later. Later I will texture this and it should hide any other flops in the model.
After the modelling is done in maya, ill export this into Cinema 4D, and using Greebler, add the panels and so on
