MASTER FX TRAINING
Creative Explorations in Compositing, 3D Design, & Special Effects with Photoshop
In addition to providing download exercise files and assets, you will also be able to download a low-res version of the final .psd layered file from the course. This gives you the chance to reverse-engineer the design and see how the layers are put together. Just be aware there might be font incompatibilities but it is only for learning purposes anyway.
I use a lot of Adobe Stock images in my projects and due to licensing I cannot provide full-res versions for exercise download. However, I do provide comp size versions for practice.
