Love it! So much attitude. The combination of the cold colours, rainy, subdued atmosphere and the angry expression of the EVA reflect that feeling of it being a brutal animal, that's being relatively calm right now, but could unleash fury at any moment. And not necessarily just at our enemies.
And I wouldn't worry about how good the drawing looks at 100% zoom. Even Leonardo's paintings probably look a bit wobbly if you take a magnifying glass to them.
