Nice job, man. Better than I could have done, for sure. Nice tone, too. One thing I did notice is that at the end of the soft part ("when you're high you never, ever wanna come down"), you were playing an A chord for the most part. (Actually A-flat, with the guitar tuned down.) If I recall correctly, you should play it as follows. (When I write G, it will really be F#, because your guitar is tuned down a half-step.)
When you're high, you never, ever wanna come down
D G D G-G-G-G-G
[so] down [so] down [so] down yeah!!!!
F G-G-G-G-G F G-G-G-G-G F A-A-A-A-A E
Anyway, I hope you didn't mind my little piece of advice. Rock on!
