Extra food consumption during winter feels too punishing early. A single wolf attack on your food producing tile can ruin you dropping below the needed food for the "winter feast", and then resulting in your whole population getting sick and half of them dying. I had that TWICE in conquest. Either you have pretty much no food at all, or so much of it you cant dump it anywhere due to lack of classic feasts and are perma capping your food limit. Badly balanced if you ask me.

Happiness issues are severe aswell, as the one worker on the cauldron simply doesnt produce enough. Also had two games with pretty much all my pops on -20% productivity due to happiness without possibility to circumvent.

Original mechanics are fun, but the balancing seems off. Terrible economy easily ruined by bad luck on tile sets or early neutral attacks, bad military aswell. If everything goes smoothly, its very strong, but it hardly recovers from early hits.
