I would rather see Grand River over on the river. This is a core city and you want that free aqua and use your traits.
I would not be in any rush to make spears. You could have gotten out some warriors, if you had gone with them instead. That means no empty city with those barbs in sight.
I would not make a granary in Niagra as it has not river and so will not be getting that big for a long time. I would rather have a worker, if the town is a 10 turn growth. IOW it can make the worker just in time for the growth.
You are commercial and AG, so workers are you friends. If Grand had been moved over, you would soon have the incense in your borders.
With no warriors, you have no scouts and hence have no idea what diection to build. What lux/resources and good looking areas are available.
If you know no others start with Alpha, then you can go ahead and do some of the first tier tech, otherwise I would do only pottery and then on to writing and trade for those lower techs.
