Bravo! *clap-clap*
There are just a few minor mistakes - стъдено should be студено, след обед is a single word - следобед, and the comma should be before че and not after. Since you're learning about commas, I could tell you that there are also two more places where there should be one - before но in "...с градина, но мисля, че..." and in front of the second нито - "не е нито много студено, нито много топло". But comma rules can be a bit difficult, so don't sweat it. I'm pretty sure 1/3 of all Bulgarians don't know them (just as I don't know the English ones) .
But as I said, these are minor mistakes. When I read this, my first thought was how you're actually starting to sound Bulgarian. You still need to remove all the "аз"-s but the rest isn't any different from what I could've written, provided I liked spring that much.
