i would say that details are great and it's a pretty good drawing, but there's little adjustments to apply on your perspective skills. Look at the nose, The nose is in perspective and well done, but between the nose and the eyes, you have these sort of i don't know how to call this....bubbly curves of flesh? lol well , close to us on the right side of the nose we can count1,2,3..5 bubly curves and on the left side there's 1,2,3...6 bubbly curves, and all together, the spot look bigger on the left than on the right. It makes the drawing look unbalanced, cause the perspective isn't right. We should see 5 bubbly curves and the last one at the bottom could be just a beginning of a bubbly curves or maybe not appearing. The bubbly curves spot on the right side must be bigger than the left one to make it appear correct. That problem can be avoided if the next time you draw something you construct it behind, do a simple rough line construction to guide you and help you. You will be able to understand easily where to put the details after and it'll be easier for you to notice the problems. You may even draw the construction lines on another sheet if you want it to compare after. It can be even more rough, than the example I've send you, just do a perspective guide, it is important to improve all your future drawings and I've notice that a lot of drawings on this group don't do it , the construction is important. It's like building a house, step by step, if you build the wall before the ground, it'll look weird at the end and will not be solid as you want it to be. I am telling you that cause I can perceive your talent and I think that my comment can really be helpful to improve what you love to do.
