It's always fun showing off to relatives, untill one of them happens to be a graphic designer and makes you look like a dunce... Cool image I love the color range of the greens. Simple but keeps you looking at it.
Sometimes the really quick stuff turns out very nicely! I like the background better than the object, and I like the object (plant?) quite well. I think you should put some neon fish in here (pun intended) in keeping with what seems to be a neon acquarium!
