This looks rly good!! If I had to be nitpicky, I may suggest adding in some sharper edges. I love the soft shading and edges you use however I think if you sharpened some silhouette lines or lines of the focal point (maybe face or jawline) it would help it pop more? But it rly doesn't look bad!

And for this particular artwork, you could include a sharper blue rim light where the blue is, it will help her stand out from the background a bit! Up to you 🥰
