Howdy! I reviewed your changes here. Thanks - your addition looks great! The attraction tag you added is a fine fit for this. Based on my research of this poi, I think tourism=artwork is slightly more descriptive. I changed it to that. However, if you disagree, I'd love to hear your opinion. Also, if you have local knowledge about this feature that is really valuable and we should try and capture that!

Let me know if you have any questions about this or mapping in general. Thanks again for your contribution, and welcome to OpenStreetMap!
