Hi. I too am an avid custom card creator!
Here is an example of one of mine (hope the link works!) https://www.dropbox.com/s/y3ejiogni6nsmqs/Dictor Supp A.bmp?dl=0
While I’m no photoshop master by any stretch I think you are off to a good start.
My feedback would be as follows-
-Dont make the info boxes transparent. The info needs to be clear and unambiguous.
-My preference is to keep the relevant info on the correct side, ie: dice pools for port batteries on the left of the card.
On a separate note, I wanted to try a SSD custom alt art but the card company I use doesn’t print in the size of the SSD unit card (at least I can’t find a template on their site). Do you have an alternative?
