Congrats. Looks much better when it's from your home country. I stayed for 6 months on my DTV (from London) and just re entered with no questions asked.
Some people used dodgy agents in neighbouring countries to get their DTV. So some IOs are suspicious about it. Nothing to worry about if everything is above board.

A few people have had to show their work contracts. Immigrations main concern is people working illegally in Thailand. I think they'll be happy with you just saying verbally that you're doing Muay Thai. But some people think/hope otherwise and want documents checked.
