some nice work here!
one thing to remember on this is, you have to add a horizen line. sky does not blend into sea in one fell gradient.
to create a horizen, i drew a 1 pixel line in blue across where i decided the horizen was/is. i then used the new 'color changer' in
psp xi to change the too white areas to more blues and greens.
i then selected the sky based on brightness and changed this to solid blue and promoted this to a new layer.
i then used the MuRa's Meister plugin filter 'Cloud' to add in a new sky. this also added a semi-opaque cast over the entire layer. i wanted this semi-opaque to help blend in the sea with the rest of the sea as well as to put the clouds over the solid blue sky.
then i simply erased the parts of the blue, semi-opaque cast i didnt want.
i also ran a usm filter on the girl and land. she was a bit blurry.
copy merge, paste to new layer, reisized for posting, done!

edit: oh yeah, i cloned out the power lines too.
