could you guarantee your project?

If I like the design I could...:)

is there still room for more submissions, or is the decision pretty much made?

There is still room for more submissions.

I have a hard time committing myself to any contest, if there isn't a certainty of anyone winning. If I do this, it would take me a couple of hours, and spending excessive time on something like that is daunting.

there is definitely a certainty of someone winning. That is why I'm doing this. I hope you will reconsider.

could I get some feedback for my submission. Also how long is this contest going to run?
