Overview
I’ve been working with this creator for about a month now, and in that time I’ve developed a strong understanding of the high-energy, story-driven style his thumbnails require. This particular design captures the exaggerated, comedic tension his audience responds to—combining bold character expressions, a chaotic scene, and clear visual storytelling to create instant curiosity.
My focus for this thumbnail was to make the situation immediately readable: the worker holding a sledgehammer, the burst pipe exploding through the wall, and the shocked reaction in the shower all work together to form a dramatic, eye-catching moment. By emphasizing contrast, sharp details, and expressive poses, I aimed to deliver a thumbnail that not only fits his channel’s tone but also maximizes click potential.
Sketch
The initial sketch I received for this thumbnail made it clear right away that it would rely heavily on strong character expression and exaggerated storytelling to work. The concept had great energy from the start—chaos, motion, and a funny, unexpected situation—but it also needed more than just cutouts and basic lighting to really sell the moment. I knew I’d have to push the reactions, refine the environment damage, and enhance the water burst to make the scene feel dynamic and believable. The sketch gave me the direction and the final design was all about bringing that chaotic humor to life.

Starting assets
I started by cleaning up both character shots in Camera Raw, making sure the skin tones, highlights, and shadows matched the dramatic, high-energy look we were aiming for. For the background, I sourced a clean bathroom environment and then built the damaged wall section manually using a mix of texture plates, debris overlays, and custom masking. The burst pipe effect was pieced together from multiple water-spray assets
Once all the foundational elements were aligned, the rest of the work came down to polish—refining edges, adding environmental reflections, and boosting contrast to make the thumbnail feel cohesive and eye-catching without losing the humor of the original concept.

Composition
Compositionally, my goal was to create a scene that feels chaotic and energetic, but still guides the viewer’s eye in a clear, intentional way. The two main subjects are positioned on opposite sides of the frame, creating a strong left-to-right narrative flow: the worker, the impact, and then the reaction.
Everything is staged so the viewer instantly understands the sequence: cause → effect → reaction. That clarity is what makes the thumbnail eye-catching without sacrificing readability.

What do you enjoy most about creating thumbnails?
I love the challenge of telling a full story in one frame. A great thumbnail is a mix of psychology, design, and instinct — you’re designing for attention first, aesthetics second. When a thumbnail clearly boosts click-through rate, that’s incredibly satisfying.
Where do you usually get inspiration for your thumbnails?
Mostly from high-performing YouTube channels in the same niche. I also study facial expressions, color contrast, and composition from photography and cinema. Inspiration isn’t about copying — it’s about spotting patterns that work and reinterpreting them.
Who is your dream client?
I’m already working with a dream client (Caylus).
