I have found myself watching some tutorial videos from this channel. I am embedding the two I am currently watching below. I plan on watching these videos a few times, but successively trying to apply the examples to my own creation after a couple of tries.

Thanks, Chris, these look like they may be helpful.
I don't have time for them now, but on Wednesday I will take the hour and a half to go through them. Although, as tutorials they will take longer as I keep pausing them to try what they suggest.
