I thought you should lighten it up a bit, from the original.
what iceblues did was great, though a bit too much lit... I would even try and darken the gravel in the front, or even blur it a bit... and get half the light that he added in.
try it out and play around, though basically it could go for a scary playground...
If you can get you're hands on a wide lens... it would look much different (in the process of getting myself a pair of lens in that sort!)
