I recommend opening these files in Clip Studio Paint to take full advantage of the 3D poses included as assets. However, if you don't have Clip Studio Paint, the PSD version is also available with the post reference.
With a long holiday approaching, I’m taking a short 2-3 day break but before I do, I've prepared my comic art layers for you to download. This will give you a better understanding of how I organize my layers. In the file, I’ve removed the dialogue, organized everything, and resized the layers for easier uploading.
I hope you find this resource useful for you! :D
