Basic problems with this shot are focus, exposure/contrast and perspective. I didn't look at efix info, so not sure what camera or editing software you have. But these can be fixed with most software since these are the basics.
I did a couple of quik fixes, just to give you an idea...
Your original
1. First thing I did was turn the exposure and contrast down.
2. Next I did an unsharp mask, to get the sharpness I wanted I had to blow out some spots then go back and spot heal, clone, and paint them out. I didn't get them all perfect because of time reasons, just enough to give an example.
3. Perspective: I tilted the photo counterclock wise so your kid wouldn't slide down the bench...lol j/k. Unless it's for an abstract touch to a photo which generally means an extreme tilt, photos need to be straight.
This is all the same as above, just with a B/W conversion
