CUt out pin and do some erasing/blank out the red stripes.
step 2 of 6
Overlay some colour on the pin.
step 3 of 6
Liquify the bottle to fit the outlines of the pin.
step 4 of 6
Overlay the bottle on the pin, tweaking the opacity. Clip and overlay the stripes on the pin. Clip the neck and cap of the bottle and tailor them onto the pin.
step 5 of 6
Block a background behind the bottle. Type text and overlay that, lowering opacity a little. Overlay some white on the neck of the bottle to simulate the white neck of the pic. I'm imagining the white to be printed on the bottle.
step 6 of 6
Place the light on the background, bopy them onto the table as a faint reflection; copy, flip and fade bottle for a reflection on the table.
