Pick up the following color #ab6622 and fill the selection. That’s how it looks by now:

Step 31

Now we will use polygonal marquee tool to stylize the inner part of the eggshell. Make a selection as below and then hit [Delete] to clear selection.

Step 32

Then select the layer with inner eggshell and with arrows keys move the selection a bit to the right.

Make a new layer and place it underneath previous one so it is actually on the very bottom. Grab the brush tool with color #553413 and paint where it is needed to achieve a 3d look.

Step 33

Get back to our base layer of inner eggshell. Make a selection of it and then create a new clipping layer.

Grab the gradient tool, choose pretty dark color, could be even one from step 32- #553413- and make some gradients here and there to make a depth.

Now you can move the gradient few pixels down and right:

Create new clipping layer...

...and pick some light color like #e7e4e2. Then choose brush tool and paint areas on the eggshell where you think light should reflect.

Select some marquee tool and move the selection a bit down, then just press [Delete] key.

If it looks better, you can set the blending mode of newly created layer to overlay.

Step 34a

So we have done our first hole. What I will show you now is nothing more, but duplication previous steps. I will use exactly same techniques to achieve another hole. I will place it somewhere in this part of the egg:

This demonstration will be faster, because it is nonsense to explain everything again. I will just show you what I am making and you must choose right parameters and tools by yourself. Believe me- it is good for you. Thanks to this you will learn to use your own brain rather than duplicating flat tutorial. Most of you have ambitions to create impressive works in future that aren’t based on any tutorial. So here is beginning.

Step 34b

Select egg’s layer. Create a selection and hit [Delete] key so you will have initiation of second hole.

Try to modify some parts of eggshell by selecting it and transforming.

Step 34c

Now we will add some 3d look to our crust. You know how I did it before, so here you have just images of progress. And for this try to not look back.
