Step 18
Merge all Pipes group's layers. except the last 3, that are the layers with the 2 white and a black line. Then make a selection like that with 0.3 feather, and go to Layer > New > Layer via Copy. Then, go to Edit > Transform and play there until you get something like this. Then Make a path with Pen Tool, like this one, make a new layer and stroke it with a brush of 3px size, like I did in previous steps, and with black colour. Immediately, make an another layer, and stroke it with white colour. Delete the path, move the white line next to the black line, and set the layer mode to Overlay. Then duplicate the layer, and move the duplicated layer at the other side of this part. it should look like this.
Step 19
Now, let's make the other pipe. Create a new group and name it Pipes 2. Then follow the instructions that I gave you in Step 14, Step 15, Step 16 and in Step 18. The result should look like this.
Step 20
This is the final step. Now, merge all your layers EXCEPT Background layer, and Contour or Shape layer. Finally, go to Image > Adjustments > Color Balance, and set these values. Thanks for reading my first tutorial. Good Luck !
