Tiny shed build

I 27M moved into a new house last year 10/24. The house came with a small shed that’s 10×20. The roof on the sides is only about 6 feet tall but the apex is 15. I live in the northeast and winters get down to 0 and below. But I need to get my swings in…

I had to make due with what I had. Here’s a list of things I’ve done:
– stripped all cross beams that were used for attic storage
– insulated the sides of the shed with r15 pink insulation
– Covered the floor with 6 mil plastic
– Covered windows with 6 mil plastic
– Hung net directly from the ceiling
– Covered the shed door with a thermal curtain
– Covered the walls of the shed with a wind screen to cover the insulation
– Bought 40” tv to be mounted

Yet to be done:
– ceiling insulation – $$
– Rug? Turf? Need something
– Would love to put another curtain behind the net to cover the unsightly lawn mower

Thoughts?
