I can see the improvement since the previous episode. Personally, the obvious gundam influence is appealing to me, but I do get tired of the stock gundam sounds. You might want to try altering them a bit to make them more unique sounding. Also, the stronger voice actors really shined in this episode, but as a result it makes the weaker ones stick out more. I feel like this will only get better over time though. One thing that bothers me a little are the mech designs. They are a little bland color wise and they don't feel different enough from each other except for minor color details, like if more than 2 characters where battling on screen, I wouldn't be able to really tell them apart.
All and all, I can tell you put a lot of effort into this episode and it shows. This has the potential to be a great series. I look forward to seeing what happens next!
