With the Magic Wand, select one of the brown lines. Hold down the Shift key and select the rest of them with the wand. Once they are all selected, copy and paste them as a new layer named lines.


Make the Merged Layer active. With the Magic Wand, click on the first section of orange. Once selected, go to Images/Effects/Inner Bevel. Use the preset of the Pillow.
Go to Brightness/Contrast with the settings of 20/10.
Do each section of the orange the same way.
When all the sections are done, go to Color/Colorize. Use the
settings in the image.
Now you can further the effect by making the Merged layer active. Click on the Retouch tool/Soften/Size 5/Opacity 100. Carefully soften the lines a little more.

*If you are wondering why you had to do the lines layer, take note of when you went back to the merged layer and you used the wand on the lines after the pillow bevel. It picked up differently. With the two layers, there is more depth and detail to the ridges of the pumpkin.
You can now merge Visible layers so we can finish this pumpkin up! Whew!
