Photoshop :: Gradient ( White <-> Transparant ) Area On Image

image w 600 h 155

background = light-green ( layer1 )

with dark green dots with shadow (layer2)

the dots are faded away from right to left ( Layer3 - gradient lightgreen -> transparant used ) .

so far no problem, or does someone a better methode? Please write me ;-)

on the left, above the backgr, a image of a 'building' layer4 ( no problem )

the result should be an image divide in three hor. strokes ( height 45-70-40 )

light-green ( dots faded away ) -> light-green ( with dots )

light-green ( dots faded away ) -> almost white ( no dots ) ( does have some overlap

where some dots are visible )layer 7

light-green ( dots faded away ) -> light-green ( with dots )

the middle stroke should have the underlaying part of the 'building' image and

background a little unfocused ( like not 100% sharp when you make a photo ) and the

middle stroke should also be a little glossy.

I know it should be not difficult.... for you, but for me, I need a little help.

Should I copy from the 'building' (layer4) the middle part, make this unsharp ( layer5). Then make the .... glossy...with a light sized border?
Or...
