Kenny over at Next Level Painting just finished this pair of super heavy tanks and he's made a series of tutorial videos for YOU to checkout.
These tanks are done in the traditional dark green of the First Legion of the Adeptus Astartes; the Dark Angels.
Checkout the fresh weathering, OSL, and super heated metal details he put into these tanks. This is some of the techniques, in additional to just basic color theory, and airbrushing instruction that Kenny teaches you in this series of videos!
Be sure to checkout Next Level Painting's tutorials, daily updates and more over on Kenny's new YouTube channel.
