It is quite refreshing from COD, Nice work
. Good luck cutting up the footage for this let's play it sounds like you will have a lot of work ahead of you.
In regards to you last video there was nothing bad about it. Unfortunately the sound was a bit low but it was not a major issue or anything. I feel the same way you do about making videos. It gets me out of bed in the morning too and it makes me happy. When I make a video and I enjoy it, I work/study harder because I get a positive push from doing something good for myself.
keep at your studies and I am sure you will get into auto engineering, If you want it bad and you wont let anything stop you from reaching that goal you're unstoppable.
