Well, from my perspective, tactically first game was lost by poor micro around 1:50. You attacked marines from the front, and while you did that, your camera was way back and you were managing your cav. So I would say you misjudged distance to your enemy, and fight started when you weren`t prepared to control it.
Agreed, I really misjudged the distance. Didn't realise how quickly he was advancing.
Plan wise you obviously did a mistake by clustering your forces. Since he doesn`t have a lot of melee, the are no reason to keep your melee with the line, put them on the flanks. Personally I would be spreading my forces from the very beginning with composition like yours. You have stronger cav, so you are not afraid of his charge, so spread all you want, take map control, and when he tries to hit you in the middle - retreat, if he chase you, his flank would become vulnerable for your melee strike.
That is excellent advise, thank you. I will keep that in mind and move to dominate the map more.
This is actually hard to explain using words - there too many possibilities, but you should not fight strongest part of your enemy army when he wants it. He had line advantage, so starting line fight is what he wanted, and you gave that to him. Instead you should keep you distance or/and use terrain, and seek for opportunity to charge cav and shogitai at the same time, and after that you bring line in. Creating opportunity for such a charge and performing it with a good timing isn`t an easy task. It is almost like dancing on the field
I like that. Makes me want to play more.
Over all - right now I belive you need sharper micro if you want to attack. To have sharper micro you need to make decisions faster, and for that you need more experience, and not live record, I guess

Or choose more defensive play style for now.
And I hope my words didn`t sound harsh, it is hard to analyze mistakes and be perfectly polite at the same time.
And therein lies the problem I think. I don't know enough about the game to make split-second decisions. In vanilla decisions are easy for me, here I don't really know that much. Your words aren't harsh, I take all criticism seriously. Especially when I ask for it. Thanks again.
