Looks pretty nice! Funnily enough, I'm building a pretty similar game – also a festival management game with some RTS gameplay – at the moment and stumbled upon yours just by chance. There also is a similar game with the same title as yours announced here: http://festivalmanagergame.com/. Anyways, it seems to be an interesting idea that many people share, so keep rockin'! :)

Looks like there is a third one in early access on Steam: https://store.steampowered.com/app/1326270/Festival_Tycoon/
Interesting how they all have similar voxel graphics.
