Some people schedule, some don't. You usually end up seeing a spike in new packs on the weekends, but new stuff trickles in most days. Personally, as someone who doesn't have a timeframe and packs are just done when they are done, I usually post in the middle of the week just so it stays on the front page longer personally. As for variation preference, I can't say for sure. I mostly do animated magic effects, and I've found that sequel packs tend to do less well than original packs. Not a significant drop, but a drop nonetheless. I took a 4 month sales range and made 9 more sales on the original pack compared to the sequel pack, so generally still enough to be worth the time put in. However, that's specifically for my brand of items. Seeing as you do character tokens, I personally would be more likely to buy extra packs if a token matched one of my player's characters appearance better. However, the amount of race/color/class/weapon combinations is so massive that it'd be unlikely to find a perfect match in a few packs, so whether it's worth your time or not just depends on your particular sales numbers. I've found extremely specific packs also do less well than general packs simply because they have less reach overall. Keep in mind, a single person only ever needs to buy a pack one time. I find themes work well if they're not too strict, or have a lot of variety within that theme. One thing you may want to think of is the fact that sprite art, while good looking, will likely be a difficult sell for a lot of people due to the fact that it'd look jarring with anything else other than sprite art. If you continue to make a wide variety of packs with the artstyle, you'll probably see earlier packs do better over time. Consider a person wanting to run an encounter with zombies, ghouls, and skeletons. Two of those are covered for your pack case, but a potential buyer has to find a ghoul somewhere else. And it's much easier to find non-sprite art than sprite-art, and somebody valuing consistency may pass on the pack as a result. So, you'll get much better results once you have multiple packs on the market. As far as experience, I sometimes get messages from people confused about some of my packs, or requests for small edits to some of them. For example, one of my packs uses pathfinder grid measurements, and someone wanted a 5e measurement instead, which is different, so I just made one item specifically for that person. Whether you do custom requests or not is up to you, but I'd suggest checking in regularly to see if any messages pop up. Anyway, pack looks good, I especially like the detailed spritework on the monsters, best of luck to you!
