Here is my rendition, as you can see I used one of the other images in the zip (forest floor) I like to use a tutorial as a guide and often experiment with it so to the shadow I added some blur using the enhance live effect and I coloured the tile green by changing the light colour in the bump map and I adjusted the brightness of each side using the enhance live effect. I think the enhance effect is under used and is very useful.
