Yes; the screen shot shows you are running cultural specialists and not working all the food, production, and gold tiles.
For all forms off science victory, growth is much more important than culture. And generating a Great Artist would be harmful as it would increase threshold.
In addition, it doesn't look like you generated enough Great Scientists.
I'm only seeing two Academies; one of which was mis-placed (at fourth ring where it does no good). If you don't have Public School yet, all GS should create Academies.
In addition, those grassland river tiles would have been better converted to trade posts sometime after Guilds before hiting the policy that gives beakers from trade posts.
Also, why are you generating zero faith??? Starting in the Industrial era you can get a few faith based Scientists and then open Order to get a faith based Engineer. In addition, this map looks suitable for the Goddess of Festival pantheon which can be spring-boarded into founding a religion for food (Feed the World) and/or hammers (Religious Community). Or instead, can be doubled down with Monasteries.
This also points to possible problem with cultural polices, you should have aesthetics for free city state friendship with every city state on the map in addition to all of Tradition & Rationalism.
Problem with that map for OCC science:
Yes, you want Mountain on a river, but in addition, you want coastal so you can build some naval exploration vessels to make contact with city states.
