I think as a step 10.5 make the white streaks set to the layer style "Overlay" or "Soft Light". White blurry marks on a dark egg look a little weird. Additionally maybe having a single light source may make it look even more 3D.
You can make whatever you like using this tutorial. Last time I made water and nature dragon This is just idea of design, there's no need of making more tutorial while you can just change the colours of gradient and add different mark. For example: [link] Snow dragon (If you are not happy of gradient's colour you can try different blending mode) Feel free to make your own projects of eggs
Thanks for help
