The first big issue with that game is reclaim. He was reclaiming while you were not. There was plenty of reclaim that you could have had but you just left your engies idle for the most part. You also didn't rebuild mex's. The two over by the hill on the top right of the map could have been yours especially with all those engies siting around doing nothing.
Your unit use could have been much better. One of the more glaring issue's in unit use was air. You had air control but you did nothing with it. You could have bombed the engies assisting his HQ or bombed his pgens into oblivion or both. Or you could have built a transport or two and done some drops. Don't underestimate the power of a drop I mean his back field had nothing. The other glaring thing I saw was that you kept trying to go straight in when you could have easily gone around. You had mobile units while he's building stationary ones. Don't attack head on when you can go around. That right there to me was one of the major reasons you lost. So many chances to go around but you continually just tried to ram straight through. Another thing I saw was that you were building mobile anti air when you didn't need to. You don't need to build mobile anti air unless you are having a hard time with bombers. Its not as big a problem with Cybran since they have the toggle ground ability but its still better to have that much more mantis.
The things you could have done when seeing that he went t2 was to build rhino's. Now I know you were more than likely trying to counter his t2 pd with MML's but building rhinos and going around the pd to attack his undefended base would have been much better. You could have also gone t2 air and built gunships. Cybran gunships murder any t1 unit and you could have sent them around to harass his side areas. He did have some t1 mobile anti air but those arnt much of a problem for t2 gunships especially Cybrans.
On the map in particular you went second air which I'm not sure is all that great of a strategy on that map(not that it cant be done). Fields of thunder is a spam map so more or less you just keep making facs and spamming mantis and reclaim reclaim reclaim!
