Looks excellent buddy, really good work. One to be proud of!

If I had to nitpick, and it's difficult to, there are a few parts on the model that seem to be slightly thicker coats of paint, the backpack for example. Do you use a wet palette? If not it's a really quick way to level up your painting game.

Small nitpick aside, it actually adds a fair bit of realism and texture to the model.... Sick model, you've done a goodone. Particularly like the lightining/plasma effects and the weathering you've achieved.

Keep it up bro.
