May I suggest that we use screenshots and not thumbnails though
Oh, I might like to add that it does have to be a released map(Though not necessarily released on L4Y)
There's mine
NOTE: The jumppad in that screenshot should be UV unwrapped correctly, but my ATI card renders the image differently to nVidia ones due to abnormal texture dimensions.
