So, a new lesson for a widebody.

As original, I took this Honda S2000:

Select a piece of the door, where the widebody has to come, go to image->adjustments->hue/saturation, and choose as lightening: -65:

Now select the entire door:

Fill the left side of the door with a black color, with an opacity about 70%:

Now select the part of the door, where before the black color was (see picture), go image->adjustments->hue/saturation and lightening is 40:

Select, again, the door and do the same as before, but smaller and a lower opacity; still with a black color, for the top and the right side of the door:

Select a part, as on the picture, on the top of the door and fill it with a black color, opacity about 60%:

You're done, a Honda S2000, with a look-a-like Porsche Carrera GT widebody:
