Love your style and detailed drawings! The earthy colours are nice and I like the proportions on the girl and the accurately drawn gun, backpack, sedimental rocks, etc. You layered the foreground, middle ground, and background in a very appealing and three-dimensional manner as well, while keeping style and lines consistent and interesting. I like how even though the colours are flat, the picture is filled with details and there is a difference in colour change in the background with the dimmer distant mountains. It also inspires dynamic action with the smoke from the gun and the dust cloud, as if she has just run away or had a gun battle. Overall, brilliant.
I almost can't even handle how much I love your illustrations. Love (and am very jealous of) your color sensibility, dynamic compositions, and attention to fun detail. Damn, son! And they keep getting better!
