You can add custom portraits of your choice for your main character. After adding it, you will be able to find it in the portrait selection of the Character Creation screen. Instructions:

• There is a subfolder custom_portraits in your game folder - the file should be put here.
• The file must be in PNG format with an image size of at least 182x216.
• Naming convention: portrait filenames should start with "male_" or "female_" as prefixes.

The path (depending on your Steam installation) typically looks like:
SteamLibrary\steamapps\common\Black Geyser Couriers of Darkness\custom_portraits.

Regarding non-standard images, as long as your picture is at least 182x216 (e.g. 400 x 400), the game will automatically clip it to the proper ratio, clipping the biggest suitable image from it.
