Excellent eye Zhyruk! This tileset was originally a commission that Zeo254 completed for an old project of mine. Later, I decided to make it available on the marketplace for a fraction of the original price, per the commission's rules that had been negotiated.
However, I just added a disclaimer to the description so that people interested in his magnificent art style can contact him directly for commissions. Finally, I made this asset free and will likely recycle the proceeds to commission other free game assets.
