DIY shed design

I present my next summer home improvement project! 160 sqft X 17' high shed with attic. If you have any advice or improvement ideas I'd love to hear them! 

I've attached the native files incase anyone wants them - structure systems and weldments were too time consuming to setup/modify so I took a simpler, more editable approach. Had to use configurations for each wall because display states don't work well in drawings.
