Nice job with the modifications! I gave your video a thumbs up on YouTube. You might have more success if you add some context to your video such as the name of the competition and what specific modifications you made. Now that I think about it, you might have meant "completion" (finished) rather than"competition" (contest). If it is a competition, then I hope you win!
I can tell you put a lot of work into your YouTube channel. I watched a few of your videos and enjoyed seeing how it's done in a different part of the world. One thing that's universal among all our cultures is that farmers are an innovative bunch.
