Hey, speaking on your fear of ruining your painting: Try not to become too attached to the art you make because you will always (presumably) be making more. This isn't to say that you shouldn't feel proud of the work you've done, just that it's important to know when to take a step back and consider your options. That type of fear can be very paralyzing and it may prevent you from enjoying art at all if it goes unchecked. Fortunately, digital painting makes that part easier, which is why it's such an accessible medium. If you can't shake off the anxiety you can copy what you have on another layer or file, that way you'll have the original to look back on. I think you are at the point where you need to ask yourself "what can I do from here?". You've already received advice about the perspective of the head, and that's something that will probably need to be changed with the sketch. Here are some options that might help: 1. Start the painting over (With the advice you've received from the other users) 2. Start another painting ("") 3. Continue working on the painting ("") 4. Take a break and do something else, then do 1, 2, or 3, whether it be quick sketching or something not related to art at all. This way you can come back with fresh eyes. Try taking the time to write down, or what will help you remember, what does/doesn't work with your painting and the steps you took for the parts that do. This way you can try replicating your results instead of having to wade through the fear of not being able to make something you feel won't be up to par. As for the hair, it might be helpful to break it down into smaller shapes while keeping in mind the direction the hair is moving and its "plains". By discerning overall larger shapes (for example, to me the top right portion of the his head reads loosely like a pyramid) then breaking those down into even smaller shapes (his hair has a lot of strong S curves). I wish I could show you what I mean, but all I have is a mouse and a very finicky computer. Remember that even though his hair is difficult to read, it is still on a three dimensional shape. Light is hitting the top of his hair and casting shadow on the bottom. Since the lighting in this reference photo is not high contrast it might be a little difficult to discern, but it is doable. It's always okay to make mistakes and to try again, especially on a digital medium for how forgiving it is. You're doing a great job!
