Oops. I have to say, that colour correction is the single most difficult thing to get right... and it all stems from getting it right at source. The only reason I mention it, is to help you in the long run. The earlier start, the quicker you can start learning from your mistakes. Im battling with colour grading at the moment and a lot of that comes from getting your colour correction right... and I'm still not great at it. I can get it down in perfect conditions... but lets face it, videos shot like this tend to never be in perfect conditions.
If you want my absolute critique... I have to say I hate the opening titles. Sometimes static titles is where it's at. I always ask myself this... "Would I see this on the TV"? If the answer is no, you are probably putting yourself in the Microsoft Movie Maker camp. A lot of the transitions and special fx that are in the core offerings of applications are there because they have to be there because of what competitor products have included. Doesn't mean you have, or should use them.
Digital zoom is generally poor unless you are pixel binning from say 4k to a delivery format of 1080. Try to avoid at all costs - I tend to allow for 10% crop if I'm going into lossy crops but I would always choose to crop from 4 or 6k footage down to 1080.
I would wager your best future purchases would be lights by the way.. the more light you can get to your sensor the better... and and as you get your head around it all, you'll realise that the last thing you want is an 8 bit camera!
