I got the texture from the actual minecraft files, and made it larger.
I took the grass onto another layer, added some shading and glow to make it look like it was sitting over the top of the dirt.
Then i got some dirt and grass photos I had and embossed them in paint.net, made their layers overlays and that gave everything its textures
Finally I added a circular gradient in the middle to give the soft light effect that I thought brought it all together.
Im not sure if thats taking an image or not, but i can show you the different pieces I used
