I normally dont take the time to do this, but.......
for those who didnt see any of the actual source...it was completely there...Each stone texture, did have the letter, number or shape overlayed several times, using several different blending modes.....you could see them much better in the large version before resizing. Yeah, I wasnt pleased with the fence either....I just painted it in at the last minute to fill the void left in that corner. Oh yeah, I assume it was noticed that the colors of flowers and grass were somewhat coordinated with block colors
Cheers!
Congrats SMITTY!!!
