Here were more than enough tipps already, so I can just repeat whats been said before. Add something like lightning, camera lens, focus, shutter speed, keywords like "realistic", "high definition", "hdr" or even write exactly what you want like "splashes", "water spilling" or "commercial shot". I tried a combination of the keywords above and got this: https://media.discordapp.net/attachments/1014675236786028614/1059737088632823888/Bier-Baron_commercial_shot_of_water_in_a_glass_black_background_dc9f5502-4c28-47f8-970f-8b551a59b45e.png this was the first try with adding the camera lens, ect. also there is more potential if you try a few times with different keywords.
