The times in the SGF may be wrong, in which case I retract this next paragraph.
You really need to slow down. You got to move

using up only 1 minute of your time? That means you averaged 3 seconds per move. In particular, after

, both you and black have a difficult position ahead of you. Yet within 4 seconds you've already played 4 stones and completely given up one of your essential groups. I don't know how you can improve if you don't take the time to think.
Anyway, I hope that didn't sound too harsh. Here's my review, in which I try to focus on the basic instincts you can focus on to improve.

I'm starting to wonder if it would've been better to have several skeleton groups across the board, like an amashi strategy.
No.
