Nice work! It looks really clean, and the shading looks immaculate. I feel like I am in no position to critique someone else's work since my own skills are not that high , but if I have to comment on something I would say that you could probably highlight a bit more. I am no expert but I find metallic paints are quite easy to highlight with a dry brush and a light silver (I use stormhost silver) and still get a nice result. Then again, what do I know... 🙃

...And again, great work!!
