I checked their NFT collection https://bitcointalk.org/index.php?topic=5379333.20 Trading volumes are good but there is only 4 items in the collection. It is necessary to increase the trading collection and add new items to it to attract more users to the collection.
Also it is very important to evaluate trading volumes on exchanges. I checked the trading volumes of Shuna Inuverse on https://coinmarketcap.com/currencies/shuna-inuverse/markets/ They are very high. It means that investors are really interested in SHUNAV2.
