By no means am I the greatest painter I. The world but I will always try to help somebody if I feel I might be able to. This model is tough and you've painted it well .let me start by saying the sharper the lines the tighter and more precise the mini will look. For e.g. Tighten up the lines and ending highlights you've drawn on the legs the smaller and sharper they appear the more crisp the model will appear. Try it out on your next model. Either way this is a well painted model kex.
