nice.

short and catchy. Me like.

Wow, this is kinda cool...

It's a little bit short, and I kinda lost the tempo after a while, but I like the effects and all. Make a longer one with more stuff, and you should have one of the songs that catch peoples' eyes...just thought, but maybe you should give it an eye-catching name too eh? I really don't think it would be right of em to give you a really good score, because you said it only took 30 minutes, and there's only like three sounds you used for this thing, and chopped up the melody and put an effect in it...but it doesn't suck though, so good job...
