I think you did a great job on this. My only crit being that the colors on the foliage look a little inconsistent in terms of color saturation and brightness. I don't know how much post work you did, but that could be handled easily after the fact.
I do have a question or two for you though. Your camera work appears to be mostly slow pans and zooms. Did you create your cameras in the Unreal Editor and then output them through Matinee or did you do movie captures within the Unreal Engine? Perhaps you did both.
I have just started learning UDK and I am still shaking the Max functionality bias that I view it through. It is challenging to say the least.
