I'll access your macro and micro for this game:

Macro: -Make your first supply depot at 10 supply not 9, making it at 9 makes you fall behind in worker production, on top of that you placed it wrong and had to cancel it losing another 25 minerals (half a worker), so a minute into the game you're behind where you could be. - From 3:27 - 3:42 you have money and you do nothing. Generally as soon as barracks is done and you have 150 minerals you want an orbital, but yours is a bit late. - From 4:25 to 6:30 your orbital command is done and you make no workers. This is macro, always have units in production as terran and always have SCVs in production. Your resources instead goes to queueing up marines (I wouldn't queue up more than 1, so 1 marine being made and 1 more on the way after, or 2 and 2 if you have a reactor). As soon as you queue it up the money is already taken away. Had you not queue'd up 8 marines you could have had a 3rd barracks on the way (so you'll have more marines) or a factory, and with 1 tank siege'd up he can't attack you. Also around 7 minutes you have 60ish minerals and over 300 gas, this is bad since you're playing a marine style (which is mineral heavy), so again this is macro. You're at 32 supply at 7 minutes, and I don't know much about terran but I'm assuming you could be around 50, just with constant workers production and unit production. - That engagement you had less than your opponent, 1 marine is 50 minerals, 1 zealot is 100 minerals, it was 14 marines (700 resources) vs 9 zealots (900 minerals) so your opponent out macro'd you. Soon after he has 3 stalkers (175 resources each including minerals and gas so he's quite ahead in macro). Now when you had an army worth 700 you almost had +1 attack done (cost 100/100) which would make your value 900, but you attack 18 seconds before the upgrade finishes so it was 700 resources vs 900 instead of 900 vs 900. - Around the time the stalkers come out it's 25 probes to 19 SCVs so again this is macro

Micro: - Nothing was wrong with your micro, if you have the alrger force and A-Move you'll normally win, but in this case you had the smaller force. You kited the zealots a bit which was good on your part and he had to run away, but when he returned he just had more stuff.

Overall: - 1 Siege tank on the high ground would have held off this attack (plus your other units). - Try to attack when an upgrade finishes so you attack exactly when you're at your strongest. In this case had you waited 18 more seconds for +1 attack it would have been an even fight. - Always create units and always create SCVs, that constant production is the main part of what makes good macro.
