About this 3D model

This is my own original creation. Made in blender. The general style and concept taken from the excellent work by Warrell72 over here: https://makerworld.com/en/models/160918#profileId-176593 I feel like there's…a little something missing to get it to the same quality level as Warrell72's stuff. If someone with a better eye for art can give me an idea how it can be approved, I'd like to hear it.
