Thanks everybody again- :)
GrandpaRD- haha thanks :) let me know your resolution if you want I can try to make a better
fitting version of it for you if you'd like.
L7 (gonna talk in photoshop-ese here, let me know if this doesn't make sense)-
for the driftwood-
I filled a layer with the "pattern" fill bucket setting, I think I used
the "rock wall" pattern. Then I tinted it the color I wanted using the "foreground" (standard)
fill bucket setting and I think I selected the color I wanted and changed the mode from "normal"
to "muliply" and fiddled with the opacity and tolerance until I got the shade I wanted.
Then I took that layer and did Filter>Distort>Liquify on it and
smeared it around until it was how it looks above- kind of wood-
grain-ish.
Next I used the shape maker/line tool to make the grey colored
lines, I made 4 or 5 straight lines, put them all on the same layer,
then did the Filter>Distort>liquify again, to smear them around a
little bit. Next I merged these two layers (smeary pattern and lines on top of them)
After that I selected the log's pixels on the original image, and
then inverted the selection, went back to the layer I just made
(that was solid pattern at this point) and erased all the pixels
that werent' inside the "log" shaped selection, So I ended up
with a layer that is just the log itself. After that I locked that
layer's transparancy and shaded it.
For the sea foam, I made a new layer and used
Filter>artistic>sponge, and then used
Image>Transform>Perspective to angle it to make it look a little
like it matched the angle of the water rather than just being flat.
Finally I did the same Select/invert selection thing on the BG to
get just the sea-foam part, and then went back to my texture
layer and erased the rest of the part that wasn't Sea-foam.
