When you have a selection, go to Select > Modify > Contract and type 2px in the input field.

Your selection should be smaller. You can now hit [Delete] button to get rid of unneeded part. To quickly Deselect press [CTRL] + [D]. After that operation you can blur outline a little (but really, a little) by going to Filter > Blur >> Gaussian blur (1 or 1.5 pixels should be fine). Also, set the blending mode of our outline layer to multiply and change its opacity to 50%.

Step 8

When you have at least one clipping layer, you can create another automatically. Just select your base layer (Here it is ‘Shape 1 copy’) and click a ‘new layer’ icon. The created layer will be already attached to our base.

Step 9

On this newly created layer we will add some highlights. It’s important to remember where have you placed your light source to avoid mistakes with lights and shadows in future. Now we will create main highlight that will help us to distribute next tones.

Make selection from egg layer ([ctrl] + [click] on a thumbnail), hit [M] to select the marquee tool and use arrows on a keyboard to move selection around. Press [SHIFT] + [ARROW DOWN] to move selection 10px down. Here is how I pleaced it:

Now grab some light color, could be #e3a977 and fill the selection (Shift+F5 or Edit > Fill). While you have already selected some marquee tool, move selection again few pixels right and up. You can also do it with your mouse if it seems easier for you. After movement press [Delete] button on your keyboard to delete the rest of layer.

You can use Eraser tool to delete the bottom of the layer.

After that go to Filter > Blur >> Gaussian blur and use settings as below. You can also change the opacity to 60%.

Step 10

Create new clipping layer. Grab the brush tool and leave same color as it was. Paint on the egg where light should reflect.

Then again go to blur filter (you can hit [ctrl] + [alt] + [F] to bring last filter’s dialog window) and use similar settings as below:

And delete these parts where light shouldn’t be as strong.
