recent thread on garden warblers, and a quick google, shows that face pattern (eye ring/lores/super) is quite variable. Leg colour also varies with juvs as they start with pale legs that progressively darken, although variation also affects the ultimate darkness of legs. Just think of Willow Warbler or chiffchaff leg colour variation. I don't think the colour of the underside of the toes could ever be used as an i.d. criterion - it is heavily affected by staining/age. For instance, I've handled tits with pink legs, red feet, yellow feet. Many factors influence this.
Bill is the biggest pointer on this bird for me. It is nowhere near long enough for a Reed. My first impression was chiffchaff.
I think the bill tip may be behind that reed making it hard to know exact shape/length.
Found this terrible Garden pic, nice looking, huh!
