@carrotnl Great start. Will be interesting if you can get it to a point where you can really recognise yourself in the image.
Overall it looks a lot more round than your head and it took me a while before I figured out what it was. It’s the forehead. Your forehead, and pretty much everyone’s, goes up more before back. In the model I think it goes back to quickly from the eyebrows. Pretty quick edit with the grab tool. Good luck with the rest of it 🙂
