I won this match but looking for feedback...

Hey everyone,

I've been out of the Starcraft loop for about 10 years but with part 2 I just have to come back!

I won this match here but feel my play was poor but not as poor as my opponents.

I would like any input you guys might have on my strategies here. I feel that I built up a variety of units through out the match, but between the constant attacking I found it hard to get back to the base and manage my units and mineral production. I also think i should have expanded quite a bit more.

Towards the middle of the game you might see that i was building up outside my opponents base. I was going to build a proxy factory but decided against it after seeing his vikings.

He tried to counter my Avatar-looking units but couldn't seem to get past the fact that they were cloaked...
