Render an image of a war deity striding across an ethereal dreamscape, captured in a dynamic stance with a vivid display of expressive charcoal strokes reminiscent of James Jean's artistry. Integrate glitch art influences and post-internet culture elements, employing a collage technique with abstract, cubist, and deconstructive touches. The form should appear distorted, sketched roughly in charcoal with expressive linework. Infuse the composition with an impressionist flair and a palette of vibrant pastel pink, blue, and yellow. Ensure the final image adheres to a 1:1 aspect ratio.
