i would suggest not doing that. just like how i wouldnt put a big panasonic logo in front of my video just because I use a panasonic camera. Or any other logos that I or the subject that I am filming are not affiliated with directly (ie sponsor/supporter) for that matter.  When I first saw the go pro logo i was like oh wow, this is going to be a professional video made by go pro, which clearly it wasnt.
sorry to be the one who has to tell you this but its a huge pet peeve of mine.
Other than the logo at the start, it looked like you had a great time and you did have some cool angles.
