To build on what LordGlenn said, here’s a visual representation of the problem. (I’m using Usenti, in case you’re wondering)
Your portrait goes into the top 3 tiles of the left and right columns, which I have represented with these blue squares. Anything within these blue squares will not be shown when imported to your rom. To fix it, simply shift the portrait, eye frames, and mouth frames 4 pixels to the right.
However, there is also another problem with your portrait. It uses 17 colors+1 background color, but the GBA can only handle 15 colors+1 background color. You’ll have to change it.
One last thing. There is a patch that lets you put your portrait within those blue tiles, though you won’t need it. In FEBuilder, it’s called “Exceed The Portrait Hackbox By 4 Tiles”
