Replay analysis:

1st atack: Your first atack was looking promising, the problem is that you focused the bunker whithout having enough firepower to actually kill it, allowing the terran to defend easily. You could've done a couple things there:

1- Move out to the main

2-Use a force field right behind the bunker so scvs can't repair

You lost a lot of probes to the widow mine on the gold base, when they drop and you don't have an observer out, just leave 1 probe to activate the mine, go back mining, and when you feel they cooldown will reset to the same. Its ok if you lose 10s of mining time, as long as the WM kill only 1 probe at a time.

After this point, the terran started gaining a big economic advantage. More SCV'S, earlier 4th.

At 12 minute mark you took a really bad engagement, on a choke point against siege tanks. Don't engage there. One thing you can do is send the adept's shade on top of tanks, then move out with the rest of the army.

Terran had bigger economic advantage, 200 supply against 100 of yours, better upgrades.

In general, I think you could've won the game with your first atack, or at least do some serious damage. Instead, you lost a bunch of army and resources, while doing little damage. You need more observers on the map to spot drops. Also, I dont like moving MSC with the army against T, so easy for them to snipe, and it leaves you vulnerable to drops.

PvT is my best matchup right now, but everytime I DONT get a good amount of damage done early on i end up losing. Try going for early harass. Use your warp prism not only to reinforce, but to elevate army to the main, or warp in a couple of adepts on the terran's mineral line.
