It's a good concept to build a coin around. Veganism is growing quickly in a lot of places.
The pitfall almost every 'good concept' or 'theme' coin fails on is making an actually decent coin.
Is there any premine, of any sort, or any advantage at all that the developer and his or her cohorts or 'early adopters' have?
Is it a fork that occurred or will occur at a specific block?
Does it include the litecoin genesis block or is it new?
Are extra coins going to be minted and held by the developer for 'promotions', pending an exit scam?
Best idea would be to make a slight improvement in emission so it is emitted very slowly and not a 'built for miners' coin like most coins.
Distribution is everything, and once the developer explains their plans for distribution it will be clear if it is a good coin or not.

Litecoin is designed to be distributed according to how much mining equipment a person can afford, so that wealthier people, like the developer, get most of the coins, and eventually the entire economy is controlled by wealthy people who will work together as a gang to extract coins from non members of their club.
Same as bitcoin

Is that the plan, copying what works in the past, but adding the 'vegan' logo?
There are some coins starting which are trying to distribute coins based on taskwork, so that most of the coins go to people who don't have money to buy mining rigs.
