Hi Mouse
You're off to a good start with this template because everything is neat and organized, so I'll just touch a bit on what I think can be improved! I also explained below why I think a certain way, etc. I hope you find this helpful.
01. Firstly, you can consider changing the firstname/lastname title to a striking yellow to match with the crowns that flank the sides of the categories, because your template revolves around black, gray, and striking yellow. Using a gray color/white color can be counterintuitive in this case because white doesn't draw the reader's eyes, and since the rest of your text info are white in color, you want to make sure that the top title is the accent color since it frames the entire template.
02. Secondly, try making the soft gray border within the template uniform. The sides don't seem to be the same width as the top and bottom, and by making them uniform, it will give your template a more proportionate structure instead of a jagged feeling that something is off.
03. I recommend adding div boxes around your category headings (personality, history, extra info etc.). Since you have gray boxes to frame the information, putting the category headings without any boxes whatsoever actually makes it feel a bit odd since the spaces are already unevenly spaced between the top part of personality and the basic character info at the top.
04. Try increasing the padding spacing for the personality/history/extra info information boxes (gray ones) by two or even three times! Right now, the text are a bit too close to the edges, and the lack of white space makes it harder for the readers to process information since everything just feels a bit too closed in.
05. Add more yellow accents! Your template looks good and err on the minimalist side, but if you want to spice it up a bit, add a yellow left outline onto the boxes like so :
Anything that you don't feel was covered by the previous two sections can be placed here. Maybe some details about their appearance or their favorite foods. It's entirely up to you! This isn't required for acceptance, and should be deleted if not being used.
I added
border:1px solid #D5B034;
to the div box.
That way, things will look more striking and special without looking overboard.
06. Try for an overall increase in the padding. White space is very important! Try adding more padding to the overall black background of the template, the inside layer as well, and along with the text info. Your template looks fairly thin at the moment, but it's not because the width is actually small, but it's because the spaces between the template background and the text are too small and therefore can actually impact the pace and readability of which the information is being read. Think of making space as a kind of breather for the reader, the easier they find it to breathe when reading, the more pleasant looking at this will be for them.
I hope all this helps! If you need to clarify anything, feel free to ask. Good luck!
