Hand-drawn ball-and-stick molecular structures of Hydrogen Sulfide (H₂S), Methane (CH₄), and Carbon Dioxide (CO₂).. Molecular models drift through dense, pitch-black subterranean air with handwritten chemical formula annotations pointing to each gas.. Composition and framing: close-up, eye-level micro view view, featuring Centered macro diagrammatic arrangement showing the three molecular species balanced across the frame at varying depths.. Scientific visual elements: Accurate molecular geometries depicted: bent shape for H₂S, tetrahedral for CH₄, and linear structure for CO₂, complete with correct chemical notation.. Setting: presented on a clean, minimalist off-white editorial background. Color palette: Pitch black, pale sulfur yellow, muted crimson red, bright white ink., hand-drawn 2D explainer cartoon illustration, thick clean black outlines, simplified readable forms, flat cel-style colors, soft minimal shading, clean educational YouTube illustration, clear focal hierarchy, no photorealism, no 3D rendering, no typography, no text, no watermarks
