Make it personal, make it your own, people will enjoy it. I enjoyed your video with your two boys, that's an awesome record of the time you had together.
There are definitely occasions where some sort of formality or structure is effective, but video enables you to break out of the mold and put the experience right in front of viewers. Personally I enjoy videography pieces that connect me with the experience, not in a paint by numbers and dot the lines sort of way, but in a creative manner that may have all or some of the following: narrative elements, symbolism, periods of reflection, adventure, and of course, a good sense of place and time. Alastair Humphreys recently shared his Iceland Crossing trek
in a videography style that represents some of what I'm talking about, it embraces the modern medium well and served as an excellent tool to act as an account for their experience.
Roman Dial has done some really awesome trip report pieces in video shooting with one or two cameras, his Magical Mystery Tour documentary doesn't have any dialogue, just a soundtrack and moving picture to share pretty killer adventures.
Just some ideas, I'm sure whatever you do will be excellent.
