Hi, @mobi72, Nice Hunt
Below is my review about your product.

Pros:

• Ability to produce immutable work that couldn't be censored by alteration or removal without compromising the entire blockchain.
• Even if the site goes down users work is recorded into the Ethereum blockchain itself.
• Sketches are also ERC-20 compatible tokens, so they can be tracked with wallets.
• Ability to make some crypto on top of sketches.

Cons:

• There is nothing negative to say about this hunt.
