The idea is, to make the shape look as it’s behind the lady, so rasterize the upper shape’s layer and choose the Eraser Tool. Carefully remove the shape from the girl’s body. I’d suggest to use an eraser tool with hard edge, however if you want to nicely blend it with the fog effect on the background and not to make the edge too sharp, I suggest to use a 20px soft edge eraser tool.
Next step is adding glow. Make sure the upper shape is selected in your layers panel and go to Layer >> Layer styles >> Outer Glow. Apply the following glow settings using the white color. Repeat the same action for the first shape as well.
And this is what you got so far… You may also apply a few chaotic white dots, using the bruh tool and add glow, this will imitate stars on the background. This is optional, if you feel your background is too dull.
If you are making a fragrance billboard you will need a perfume bottle, but again this could be replaced with any other product you are going to “sell”. We went with this fragrance bottle from sxc.hu. Most important is to crop it properly and then find a good location for it on your billboard.
Once you have located it, it could be a good idea to add a little transparency to the glass so that you’d see the grass from underneath it. We just duplicated the layer and set one of them on “overlay”, the other on “soft” so we can see the grass through yet the bottle does not become semi-visible.
After this, make a new layer on top of all the others, select the brush tool again, using the “dune grass” brush shape, and add a bit more grass over the perfume bottle itself, to create the illusion as it sits “inside” the grass field. That’s it. Add text and your Fragrance Commercial is ready to go up on New Yorks’ streets!
