Art style: Pencil Sketch.
A vertical eye-level shot from behind the trio as they take a collective step toward the glowing portal. The light from the gateway washes over them, turning their backs into silhouettes while illuminating the ground in front of them with indigo and silver light. The hamster points a tiny paw toward the center of the vortex. The atmosphere is adventurous and climactic, with a dominant indigo and silver palette.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Pencil Sketch" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Pencil Sketch". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Pencil Sketch" idiom, not in any other medium.
