Re: A new crafting building for the units from the town hall
The red lines are emphases of the lines of that building. The two lines to the top right give the first vanishing point. The lines are totally inconsistent. Except for the vertical arbors, none of the other elements match. Look at the other buildings, you will find a clear design rule in all of them. This is not give in the present building. It fits perfect among the leaft out buildings but, well, that are the buildings that are left out. So I think the current building does not fit.
The next question concerns the needed resources. The axe is made entirely of iron, why the wood? If you think of the smithing process, you would rather need coal than wood. At least that would follow the intrinsic game logic.
2 iron bars is way to cheap, even 3 iron bars would be too cheap (remember, the already weaker swordman costs 3 iron bars plus some coal plus 2 buildings and workers). 4 iron bars and the building won't work efficient because after the worker has started, there have to be filled in at least 2 more iron bars until the next axe can be produced.
