I however, have a small question. The effect seem to be less effective at higher pixel maps.

Is there any way to do something about the? Thanks in advance. And once again thanks for an awesome tutorial.
It is the noise scale. The default noise filter in gimp is proportionate to the page size, so you are limited...

I have previously recommended the felimage noise plugin as it has better control and types of noise and will work just as well on a smaller mas as a larger map.

Also, Old Guy's tutorial is another great method with different but also excellent results.
