Excellent stuff!
I've just watched all three in order - they're great. Good story, good characters, and the fighters are all amazing.
The only thing really letting the side down a bit is the voices - you're a one-man operation and so you're trying to do the voices of half a dozen characters. Unless you're Mel Blanc, that's a tall order. This would easily be one of the best series on NG if you got one or two people in to help - at times I have a bit of trouble identifying which character is speaking.
I can't wait to see what happens when the Kiwi space force faces that Zerg mutated monster!
One last thing - the 3D models of the Starcraft ships are amazing - the Protoss Carrier especially.
