I purchased both of your packs, and on November 3-4th, I streamed Unity Game Development on Twitch on a game project using your art. I did the stream for the Extra-Life charity 24 hour even and gave you credit for the graphics and art.
I want to continue this project, but need some other assets in this style for that. So I thought I would propose those to you, to see if they were something you could complete, so that everyone on itch.io could buy them as well.
1. An Items pack, we have a very limited amount of items in what you have done in these two packs. We need more weapon and armor types, crafting and other items. Think of things an RPG would need to be complete.
2. A Creatures/NPC/Boss pack, again we have 5 base Creatures, only 2 NPCs and 0 bosses in your two packs. Your Zombie, feels off compared to the other creatures. This could be broken down into a couple of different packs.
3. More Tile Art Fluff, you have a couple rocks, a few flowers, a bush... but, I feel we need more of this type of ground clutter to make the maps seem less empty; to allow for more richness in look and feel.
4. We also need UI elements so that we can build a user interface, for things like: inventory, character, stats, spells, skill trees, etc...
Of course all of these need to maintain the same look, feel and art style of your other items. I feel some of your Dungeon pieces, break into looking futuristic and drift from the rest of the fantasy items.
I do love the simplicity and style of your art and let everyone on my stream know it was your art, and showed your itch.io pages. So I hope this helps you some.
I hope you take my feedback as constructive criticism; I did not mean to offend in any way.
