Marginal, but you have room to make improvement.
For fooling around, this wasn't awful, but it could have been a lot better.
1) Your sound samples were way too loud. I had to download the file and listen at 20% normal volume for it to be at an acceptable decibal level.
2) A decent song will sound somewhat organic in rhythm; yours seemed almost mechanical to the point of me thinking a robot was conducting it (yeah, I know, Megaman & robot, har har :P).
3) Your sample chioces were alright, but they could have been varied more. Maybe something like a faded choir in the background around the middle would spice it up a little... that's just an example; it's your choice in the end.
I do hope to see you attempting more songs though; try to give them a little more effort though before posting them; it'll be worth it. :)
