Don't drop animations ever. Just pop 'em on the side and save 'em for later. I've had projects that lay dormant for half a year sometimes longer before I finish.
Ya lose the drive or motivation for certain things sometime. It just takes time to get 'em back or a few months of R&R to recharge the artist within. It looks good. Don't drop it. Be confident.

You should keep going with your animation, its lookin' good. I think the reason you probably don't get a lot of responses is due to two reasons. 1: People may not have anything to add and 2: Update your user Pics, your talent at drawing is obviously up to par for better pictures. People do read your stuff, and your first idea was a really good one. It gave me an idea also for another interactive story. What if it was an action one that had multiple choices that you click on which show flash clips of the action that progress you through the story. For example, kick door, go around side, climb roof. So you pick kick door. When the door is kicked, monster or something tackles him and they fight, out comes a knife. Bite, head butt, knee. The store is a soldier/space marine/mercenary is just trying to get home. Spend some time on making some really good animations like your Firy Firebolt scene and I think it would be cool.
Sort of an interactive thing for adults. The other two ideas are too vague to give you any ideas or judge em. If you are not feeling inspired, jump on the forums and just talk to people, or try different venues, like music, or just art/fan art. Something thats fun and shakes it up so its not the same stuff all the time. We all become uninspired all the time, but don't lose steam, and push through it :D

Thanks for the awesome response dude! I have never actually seen you, but you have good ideas. Also great patience for writing such a constructive comment. Considering that I am not this huge artist, just this local dimwitted user.
Anywho;
1: Nah I know, I write a lot of crap.. I should start writing about them, in order to get responses. It's not my wish to get a bunch of comments like the big artists, my wish is only to get some sort of "hm, do this do that to improve". But most of all, get to know more people in the genré of animating and such. Since I don't know anyone in it.
2: Aw man I'm too lazy. Someday! It's inspired from the poster to Vanilla Sky, I think that's why I like it.
(3): Yeah, thanks. This confirms my belief. This hasn't really been done before neither. I also want to introduce the NG-users to the very weird, but awesome dance genré known as Hardstyle. And try to use it, and animate it according to the track and it's BPM.
Perhaps our paths will cross again man! Till then, peace out!
