ya well the videos i make are usually about not much cool at all, i just try to do stuff to make them as great as they could be for a little job.
something that stood out:
you obviously spent so much time/effort building the batman "t-cart" you could make more videos like
-updates
-coldstarts
-little parts that were unique, explain their functions
-try new things, such as on board helmet camera/ mount camera on cart somewhere
-breakdown of cart, what all functions are and how you put each piece together and roadblocks
-reviews of products, tools, engines
theres so many more but the best way of translating your thoughts into words is always the better video i guess.
when i make some of my vids i might actually do it over and like recording a voicemail the more times you do it the better you get at it.
some of my vids are edited some are not, i just got my own account recently (used to share with friend) so i dont have a lot right now.
if you add music, you want to pick good or else people will leave comments saying that the music ruined the sound of the engine, etc.
