Please don't submit unfinished things to the Portal. That's not what it's for.

If you want feedback, tips, and ideas, that's fine, but this isn't the best place for this. The Portal is for finished items. The Forums are what you want. Load this into your Dumping Grounds. If you don't know, it's the third icon from the left at the very top of the page when you're signed in. It looks like a bucket with an arrow pointing down. Once it's loaded there, copy and paste the link into the Forums (Community>Forums). That way, people see it and give tips, which is what you want, but it's not in the Portal, filling your account with low scores or blams, which you don't want.

The Portal isn't for tests or unfinished items, tho: http://www.newgrounds.com/wiki/help-information/content-submission

Good luck. :)
