Yeah. Unfortunately it's difficult to get noticed on Itch io which is a shame because I think your asset pack is very cute and well made :) The asset pack covers all the basics so that's good however the only real "problem" it has is that it comes across as a little generic. Some of the asset packs that I've seen that I would consider buying from if I had money :( are the ones that look stylized with their eye-catching images and unique font. Take for example this asset pack: https://cupnooble.itch.io/sprout-lands-asset-pack. First off, it has a nice background image. I understand that you have a snow theme going on and you shouldn't feel the need to have bright colours by default but maybe if you had a stylized snowflake or snowy mountain as a background? If you're anything like me, having something visually stimulating will definitely draw your attention. The more visible effort is put in an asset page the more people will have trust in your product. It's important for a font to be readable but I would recommend the pixel font that's often used for pixel assets. Everyone is using it so there's gotta be something that's working. Also I've seen that whenever there is a titles that the page discusses such as "License" or "Updates" making a the title font bigger and maybe even adding a cute little picture next to it can really spice an asset page up. Another thing I'd recommend is having a section where you tell the buyer what is in your asset pack. Saying something like "this pack contains four different icebergs, two mountains, these animations" etc. People are wary about buying things they have little knowledge about so try and give them as much information as possible. I'd also add an image that has the pixel objects as stand alones rather than being in an environment. So that people can see in detail what each object looks like on their own (remember to add a watermark to the image). So something like this:
Adding tags is also really helpful. I'm not sure what the maximum amount of tags you can have but try and use every relevant tag so that it appears more in searches. Lastly I would recommend making more assets/projects whether they be free or premium since the more projects you have, the more it will show up in searches and therefore the more people will be exposed to them. Also this is kind of a little too much feedback but if you're going to make more asset packs in the future with a price I'd recommend making a couple that aren't super specific. The snow asset is nice but it's quite a super specific situation that needs a super specific game. So maybe making a grassy texture, forest, animals and people can help get more buyers since they are often used in these pixel RPG games, y'know?
Keep in mind I'm no advertising whizz and take some of the things I've said with a grain of salt. But it's at least a step in a somewhat better direction. Good luck for the future :)
