Pupdude, I'm going to ask you not to worry so much about your build's reception. This is a rather small forum, so frequently it can and will take days for something to be downloaded or even commented on for the first time. A lack of downloads in itself is not even a good representation of the interest in a build - many members, myself included, can appreciate and like someone's creation without downloading it into their game.
Speaking of your Cardboard Box, I like it
. It's a nice cheap compact design that I could see myself using for Legacy games where Sims start out with very little money. If you're capable of more complexity by all means post more of your work, but otherwise it's a very respectable build on it's own and no one is going to accuse you of not putting in enough effort.
