Just like the previous step, load the selection of the Chain. With the linear Gradient Tool (G), click and drag on the edge of the Chain to create a shadow. Repeat this step on each chain that overlaps with other objects.
Keep adding more details. Now we're going to add some wires next to our Props. Open the Wire image. We are going to extract the part of this wires from the image using the Pen tool (P) and start tracing the wire until you get them right.
Now once you are done with it, go to the Paths panel, right click the path we created, and choose Make Selection. Leave the Feather Radius to 0. Copy the selection (Ctrl+C), and Paste (Ctrl+V) it to our canvas. Add a couple of adjustment layers below to fix the tone properly and use the technique in the previous steps to bend the wire and to create shadows.
Let's now focus on the body. Import the Crack texture into our canvas, and press Shift+Ctrl+] to bring the layer to the very top of the stacking order. Create a new adjustment layer in the Layers panel and select Hue/Saturation. Make sure the clipping mask button is turned on. Then slide the Saturation down to -100 to remove its color, and change the layer Blending Mode to Overlay.
Add a layer mask. With the soft Brush Tool (B) carefully erase the unwanted parts of the crack. Try to preserve as much detail as possible. Adjust your brush size to reach very small areas and use the X key to switch between black and white as you paint. Copy the layer and repeat the process to the other parts of the body.
Next, we are going to add another details to the body. Import the Metal Texture 2 image, and with the Lasso Tool (L) select a portion of the image, then click on the Add layer mask button in the Layers panel. Create a new Hue/Saturation adjusment layer and turn down the Saturation to -100, then Set the Blending Mode to Soft Light and reduce the Opacity to 66%. Copy the layer and place it in some other parts of the body. The Opacity depends on the which part of the body you are going to put the texture. In the darker area, reduce the Opacity to 30% to lessen the effect. Now grab the Brush Tool (B) and with the soft-edged brush, erase the unwanted part of the texture.
Before we finish this piece I thought it would be nice to add one more little detail that would make the piece little bit more interesting. Open the Rivets image, and with Rectangular Marquee Tool (M), select the rivets and drag it to our canvas. Bend it just a little bit with the Puppet Tool to follow a curve of the body. Press Shift+Ctrl+U to desaturate the image and set the layer's Blending Mode to Overlay. Also, erase the edge of this layer with soft eraser, so only the rivets part of the image remains. We can duplicate the layer to enhance the effect and play with the opacity to get the desired effect.
We have reached the last step of this tutorial. If your result is pretty similar to mine then you are doing great job so far. Let's add a Barcode image and put the layer beneath the Metal Texture 2 image, then set the Blending Mode to Multiply. With Rectangular Marquee Tool (M), delete the upper part of the Barcode. Lower the Opacity down to 51% and apply the Warp Tool we have learned earlier to follow the contour of the body.
