Realistic Photoshop Sketch Enhancements

I have six scanned sketches that need a subtle yet polished digital pass in Adobe Photoshop. For each piece I will provide a short brief; the overarching goal is to keep the drawings looking hand-rendered while refining them for presentation.

Work involved
• Add small, realistic details where noted.
• Vary line weight to bring foreground elements forward and push background elements back.
• Cast convincing shadows that all read from a single, consistent directional light source.
• Apply marker-style rendering and gentle airbrushing to unify tones without losing texture.

Please work non-destructively—layer masks, smart objects, and clearly labeled groups will make review simple on my end.

Deliverables
• Six finished, high-resolution files that respect the original proportions and the brief.
• Layered PSDs (or equivalent) so I can toggle each enhancement step.

Acceptance criteria
Every file should show lighting governed by one clear direction, smooth transitions between marker and airbrush work, and line weights that enhance depth without overpowering the sketch. If this aligns with your skill set in Photoshop, I look forward to seeing your approach.
