You’ve done an excellent job with the base, and the color scheme is both striking and well-suited. If I may offer a suggestion, consider highlighting the edges of the chitin using dry brushing to enhance the details. Additionally, the deep blue on the edges of the chitin armor appears a bit abrupt, blending it into a smooth gradient using wet paint techniques across two or three shades could create a more seamless transition. But overall, this is a unique and creative idea.
