Open the second crocodile photo again and place it in front of the car. Using the layer’s mask erase all the parts that you don’t need. Be careful to leave the front wheel uncovered.
We need to create 3 clipping masks to adjust the crocodile’s colors, so go to the Adjustment layers-Photo filter, Adjustment layers-Color balance ( use the presets as you see below) and Adjustment layers-Hue/saturation.
In this step we will cover the car with crocodile texture. For this we will use the texture from the crocodile’s back, so using the pen tool cut out the back the marked part.
Clip this part to the car’s layer and leave only the part that covers the door. Remember to leave out the upper wheel. This wheel casts a shadow on the door so using the burn tool we will create that shadow. Use the image below for guidance.
Now we will cover the roof top of the car using the same crocodile texture we used for the door. Place it on top of the roof and clip it to the car’s layer. Erase the part that covers anything else but the roof top. Next change the blending mode to soft light.
Now we will need to cover up the metallic line under the windows, so we will use the same texture but we will change the blending mode to overlay.
Next we will cover the back door using the same texture, clipped to the car’s layer. Go to the adjustment layers-curves to darken the back door.
Now you see that there is a small part of the car’s hood that remains uncovered. Cut out the back of the crocodile. We will use the same texture to cover the part in front of the windows .This layer should be placed under the crocodile’s one. Erase on the layer’s mask some parts to fit better.
Return to the crocodile’s layer to cut out the texture on his back one more time. We will only need two rounds of spikes to cover the car’s hood. After you position the texture, use some burn to add some shadow. Duplicate this layer and place it under the first one. Use the image below to see how this should look.
In this step we will cover the last parts of the car that are still left without texture, so go to the crocodile’s layer, because we will use his back again to cover them up. Cut out one row of 6-7 spikes. Use warp to curve it a bit so it will fit on top of the spare tire. After you are done, double the layer and place it near the first one. Now this part is covered. If it doesn’t really fit , don’t worry, because we will use the liquify filter soon, to correct this.
There is only one part left from the car, that remains uncovered. So we will use the same technique, as we did in the step before. Using the texture from the crocodile’s back , cover this area. Use the image below as a guidance.
Now that the car is covered we will attach the head. So, open the last crocodile photo and cut it out. Place it under the body’s layer. Create a small shadow . Fill it with black and set it’s opacity to 15%.
Next we will use some filters to blend the head into the picture, so all the next adjustment layers will be clipped to the head’s layer. Go to the Adjustment Layers- Gradient map. You have the presets in the image below.
Adjustment Layers-Photo Filter.
Open the bird photo and place it on top of the crocodile to add some color. Cut it out using color range.
In this step we will make some small fixes, but they will make the whole picture look more blended. So cut out a row of spikes and place them at the door. Next add some light using a basic brush, with white ( opacity 40-50%). This is a small detail but it will look better in the end.
