I watched through the whole thing, and it was a pretty fast paced match. But I think your opponent might have been a bot, because watching from that pov with viewlock on, he didn't look human.
few pointers: more military buildings. You built some at the start, but then stopped, whereas he kept building em. This created a bottleneck for building your troops, i mean just before you resigned you still had heaps of everything left.
More siege, and guard them. And don't use archers against buildings if you can help it :S
