i love the idea and alot of the outcome, maybe blur the building a little in the background and some other parts to add depth and un-sharpen other parts, imo the text suits the tag, just move it closer to the bottom of the tag and remove those blue dots at the bottom of the render, also maybe add some more lighting to the left of the render as on the render its very strong but on the tag it isnt

Overall good job, i like it, if you make some changes i could love it

I made a tag with this render, here was my outcome, i prefer yours haha
