Barletta Luxury Pontoon 3D print model

Put this together for my father-in-law. It is 3 or 4 different models spliced into one to try to get as close to his boat as possible. It is my first attempt at a 3D Model using the software that I have available to me. The pontoon cover had to be reinforced, so the two awning supports that aren't connected to anything can be removed after printing.

I am new to the model creation from scratch, so I will take any advice or recommendations to get this model cleaned up.

Thanks everyone, happy printing!
