Hi there! I'm quite new to itch.io but hopefully that is not a criteria to give feedback . I took a good look on it and would share a few thoughts about - strictly from the "curious passer-by" viewpoint and with all my knowledge I have on design.

First you want to ask yourself what is you want the visitor to feel and see when he first arrives on your page. As a visitor I click on your profile link for a reason, that is most likely curiosity. I clicked because the name Halfling Caravan Games suggested that yeah this guy is involved in something with D&D, is it maybe an adventure module or a story-driven game about halflings? Then I arrived at your page and my first glance was the girls radiating warm smile in the header image ( cheers to the artist by the way!) My second thought: the title says Writing Adventures, Games & Hacks. So I scrolled and read the first two paragraphs. This cleared many questions up - a veteran GM with many ideas and currently working on his own system. Then I read further to find out what exactly Beta Max is. To be honest I'm kind of a hasty reader, so first I thought it is a digital game engine. I don't know Old World of Darkness you referred to, not even its genre (tabletop RPG?). As I read further it reveals to me that this is technically a tabletop core games system with multiple campaign settings (you wrote "skins") and adventures to play through.  But there are no photos, so I have no idea if this is a tabletop game core rulebook in digital format, or a physical one. This info only gets to me if I click on the "More information" section on product page, which means this info is hidden from an average internet surfer who just scrolls through quickly.

I'm sorry if I misunderstood something, these were my initial thoughts on visiting your profile page. Now some suggestions if I'm allowed.
- Make your header clean, with main title in focus (maybe place it in the left, this is generally what people read first), and let sub-title serve as a short explanation, with smaller font size.
- Header background images should be connected to your project as closely as possible (nice art is OK, if you have permission to use it)
- Include images of the product in the state the end user will experience or use it- for example, if this project involves tabletop gaming, a bunch of dice or printed character sheets, or people playing it. Think of it as a promise to your products future users :)
- Rethink color palette - longer text on saturated background is harder to read. I would suggest something like a light brown or a washed yellow, similar to a parchment  paper.

I hope this wall of text won't discourage you, I really tried to be useful :)
