Serotonin Studio mockups are high-resolution, layered PSD files designed for use in Adobe Photoshop. Each mockup is built from original photography and includes an editable Smart Object that makes it easy to add your own artwork while preserving the lighting, texture, and details of the original scene.

Open the PSD in Photoshop, double-click the Smart Object labeled “Smart Object (Add Artwork Here)”, place your artwork, save, and return to the main file. Your design will automatically appear in the scene. Each purchase also includes a PDF User Guide with additional instructions and tips.

Yep. That’s what the free ones are for. Our free mockups use the same general file structure and production standards as our paid products, so they’re the best way to see if Serotonin Studio mockups are right for you.

Free mockups include a Portfolio License unless otherwise stated. If you want to use a free mockup commercially, you’ll need the appropriate commercial license. See our License page for details.

Yes. Serotonin Studio is an independent design studio, and we occasionally take on select branding, digital, and other creative projects alongside our product work. If you think we might be a good fit, get in touch with some details about your project, timeline, and budget.

Our mockups are designed for Adobe Photoshop. We recommend using the latest version for full compatibility and optimal performance. Other software may be able to open PSD files, but we can’t guarantee that all features will work as intended.

Each individual mockup includes one high-resolution, layered Photoshop (PSD) file and a PDF User Guide. Mockup Packs include all PSD files listed on the product page along with the PDF User Guide. Exact file specifications, dimensions, and other technical details can be found on each product page.

Your mockup isn’t broken. Some files include a lightweight preview layer at the top of the layer stack to help keep the downloadable file size manageable. Simply hide or delete this layer to reveal the full mockup underneath. Instructions are also included in the PDF User Guide.

Absolutely. That’s what they’re built for. Open the designated Smart Object, place your artwork, save it, and the mockup will update automatically. Each download also includes a PDF User Guide with instructions.

File sizes vary by mockup and are listed in the Technical Details on each product page. Our files are built from high-resolution original photography and include editable layers, Smart Objects, masks, and effects, so some PSDs can be fairly large. Make sure you have enough storage space before downloading.

Yes. You can resize, crop, and adapt the final composition to fit your presentation. We recommend keeping an untouched copy of the original PSD and working from a duplicate, especially if you plan to make significant changes.
