background tips
k, so i just recently started using gimp after a two year hiatus from a semester of digital design (we used photoshop) so now i am making a cover for my portfolio.

on my cover (attached image) i am trying to make the words and splatter effects take on the cover of the brick wall behind it, so it actually looks like it is painted on. can anyone give me any tips, or direct me to somewhere where i can figure this out? i have been looking for an answer for about an hour now Tongue the words are all in their own layers. (if that matters at all) thanks for the help!

RE: background tips
Use the selector a the top of the Layers list to put the layers in "Overlay" or "Soft light" mode.

You can also try to extract a bump map from the bricks (duplicate layer and desaturate) and apply that bump map to the overlay layers.

RE: background tips
Did a couple of tests:

What works best here is "TEXT" layer in "grain merge" mode, after applying a bump map on it. To obtain the bumpmap, duplicate the bricks, desaturate, and use the Level tools so that the bricks get black and the mortar white, with a rather high contrast. When applying the bumpmap, invert it, and tune the lighting so that it matches the one used on the wall (angle and softness).

Just for the fun I added a bit of random erosion (layer mask filled with RGB noise, slightly blurred, thresholded). Once the mask was applied back, I blurred the text slightly (2px).

RE: background tips
Can even be a bit better by randomly desaturating the paint:
