Nice time-lapse. I would suggest making something on a multiplayer server and getting someone to film you, so you can see the building being constucted from an external view. The camera would be in the same position throughout the video.
Do you know how to make HD skins? If not, it doesn't matter.
Would it be possible to make an adventurer-type skin (like Bear Grylls, or something)? If it's really good I'll use it as the default skin for my texture pack.
