MULE drops can be dropped on minerals and they will auto-mine. I've seen you drop them quite a bit away from minerals and sometimes forget about them (wasting the duration and overall potential minerals)
Second, your Hellions come into the game a bit too late in my opinion, they excel at early game harassment vs zerg since they make quick work of lings and drones (ineffective vs roaches and hydras, which is what he had during the point in the game when you started getting more hellions) so going with a tech lab to tanks or even just spending the minerals on 2 extra marines would have been better.
Had a lot of floating minerals, could have used them sooner to mass more marines
Low gas income due to lack of workers actually gathering gas... Always make sure you have 3 per! Could have pumped out better units to counter things.
As for your problem with broodlords/hydras/roaches (even though you shouldn't have give him enough space to tech that far!) The best solution I see is marines/tanks D with some Vikings to take out the brood lords.
Well that's my analysis. I am not in beta but I do know my way around the game so you can take my advice lightly.
Hope this helps a bit.
Edit: How could I forget! Ravens! They do a great job for support with auto turrets/point-defense drones but they really own the clumps with their Seeker Missiles.
