Well, I honestly don't know. While I'm sure your advice and such is helpful, I really don't know if I can actually do it. I know it takes time, but it's not time that I have. Since I can't get my laptop working for the life of me, either it getting a virus or simply because it's an entirely faulty unit, I have to use the family PC.
And to be honest, it's hard to work on delicate stuff like that, constantly being asked "What's that? What are you doing? What are you viewing?" almost non stop. It's one of those things you can't control, and it never really stopped even when I had my laptop. I get almost no privacy. It's not really a problem of trust if that's what you're wondering, but it's just a problem of being over curious I think.
I've tried my hand at spriting many times, and it's never really turned out right. Mostly when it comes to making animations for a sprite. Even with using the method of placing the sprite over another and trying to sort of trace it doesn't really work for me, I'm not at the level needed to actually change the sprites properly. I'm just not.
