Caspian Gull?

The second image is definitely a Herring Gull. The first looks good for Caspian or Yellow-legged, but I always struggle with separating them. The white head certainly makes me rule out Herring. The bill looks parallel edged, but doesn't look particularly. Young Caspian gull should show a mottled shawl, which isn't obvious. I also think the eye is too big and has an obvious smudge, which leads me to think Yellow-legged. However, I tend to rely on more expert gull watchers to confirm the ID of these species
