Start by creating a file in Photoshop at the size of an A4 (210mm x 297mm) at 300 dpi. Once created, fill the background with a dark gray (# 424242)
After creating the background, the first thing to do is extract the boy by using your favorite tool. I made a selection using the Polygonal Lasso Tool (L) and then applied a mask. No need to be very precise on this selection, because the boy will merge with the rest of the image. In the area of the feet you can leave some details such as the shadow between her legs, and remove the excess using a soft brush (B).
Now let’s create an aureole for the angel. Create a layer called aureole and with the Elliptical Marquee Tool (M) make an oval selection and fill with white.
Make another selection within the aureole and delete the selection. This way you will get something like that.
Now we need to create the inner of the aureole. Create a new layer, place it below the aureole layer and name it “aureole back. Make an oval selection and fill with a light gray (# b0b0b0).
Use the Burn Tool (O) in Highlights mode to create the lights and shadows of the halo. In the end you should have something like the image below. After that, group the two layers of the aureole to keep your file organized.
Position the halo over his head.
Now we need to make the shadow of the halo. Create a layer and position it above the layer “angel.” Right click on the layer and create a “Clipping Mask.” Set the blend mode “Multiply” and with a Soft Brush (B) paint the angel’s head trying to simulate a shadow.
Open the image of the wing, cut and place them behind the angel.
Create a New Layer, set it to “Multiply” and then create a “Clipping Mask”. Use a Soft Brush (B) with Black and paint over the wing to create the shadow of the boy. Don’t forget to group the “Wings” layer and the “Shadow” layer.
Open the city file, desaturate it using Command/Ctrl + Shift + U. Then go to Image > Adjustments > Levels to darken the image.
Now open the bridge file, then go to Image > Adjustments > Levels to brighten the image.
After that, position the bridge behind the angel and the city like the image below. Group the two layers and create a mask to hide in the image edges.
Now it’s time to set the ground. Take the image ground and desaturate it. Place the ground like the image below and use a layer mask to hide the edges.
Open the Spatter image and desaturate it using Command/Ctrl + Shift + U. Invert the image color with Command/Ctrl + I. Then go to Image > Adjustments > Levels. At the levels window click at the black eyedropper and click in the black area as shown in the image.
After that, copy and paste the spatter in your main file. Set the blend mode to “Screen” so the black will become invisible. Then hide the borders using a Mask or the Eraser Tool (E). Make other copies of the Spatter layer and position them to get the result below. (open the link above)
Now let’s put more details in the Background. Create a New Layer on the top of the Background and use a Soft Brush (B) to make a soft white glow.
Place the Clouds on top of the Background layer, then desaturate it using the Command/Ctrl + Shift + U. Go to Image > Adjustments > Levels and use the Black Eyedropper to set the black point in the image as shown below. After that set the Blend Mode to Screen.
Duplicate the Cloud Layer and Flip it Horizontally and then place it like in the next image. Group the Clouds Layers and set the Opacity to 50%.
Place the Birds image. Desaturate it using the same technique as shown previously in this tutorial. Then go to Image > Adjustments > Levels and use the White Eyedropper to set the White Point of the image.
