Practicing analyzing my own games. Short game 16 moves

So im starting to analyze my own games and i was wondering if i was doing it right. Its a really short lost game. 

My first step was to analyze it without an engine 

Now after engine Analysis

After analyzing the game by myself and then with an engine its reccomended that i categorize this loss so that i can start seeing patterns in my games. Therefore i have a check list. 

Time management- too fast. I spent 6 minutes out of a 15 minute game. 

Poor calculation- needed to think more and picture the positions a few moves ahead but blitzed the game which made it a fail

Poor defensive effort. played the blunders 13.h3 and 15. Bg3 which both lose because i didnt calculate black's options well enough. 

From my experience, yes you are analysing correctly, also this probably belongs in the analysis forum.
