Self Promotional Animation

So, I have had this idea to do an animation for self promotion on my website, but I was never able to because I had to withdraw from my flash class that was teaching me. So my dream went dim for a bit, but now with this final project is has been revived. I want to bas it around a song from Hybrid. My only problem is it's two minutes and four seconds. I know its long, but will that four seconds over overtime be ok? What do you guys think?

I don't want to just do this project for the sake of this module, it is something I have wanted to do for about 2 years now. This is the perfect opportunity and I am going to take it, four seconds over or not.

It is way more complicated than I would like, but I am going to work with what I have and make what I have dreamed of. It is an animation made completely of lines. You will see the lines being drawn out and creating visuals and walking through a journey of where I want to be and who I am. If all goes well, I will hit the nail on the head.

It is extremely hard to sketch out my sketches because everything that needs to be sketched is all moving. But I have attached my logo of my brand. Sometimes it is hard for me to put my ideas and sketches on paper because I work so well in my head. Its a strange way and a lot of people say it is good to write down and sketch your ideas, but unfortunately for me that's not how my brain works, and I am a very visual person so it gets frustrating.

Any ideas on how to help me put my sketches and ideas on paper?
