u/Dazzling-Tap-6442

I recently tore down my grandmothers rotten old shed and i am building the shed based on the stud design of the old shed, designa online and some alterations to fit in the garden corner neatly. I am using treated wood for the main beam and column parts but i am economising by reusing wood recovered from old projects. This is the standing frame. I intend to put in a lot of diagonals front and back to stop racking and even sheath with some ply we have before putting shiplap outside. This will be the most expensive cost.

I want to make a truss roof and put marine ply and nail on felt just for the challenge. I have two windows going in that are single pane and the door is already made.

Any comments or improvements?
