The following advice is from Swistle: Baby Names (swistlebabynames.blogspot.co.uk) and is American in context but just replace the names with Ava, Ella, Ellie, Eva, Evie, Eloise, Layla, Leela, Leila and Freya and you'll get the idea:
'The thing to avoid now may be names that sound similar to a bunch of other names: Kylie, for example, in a classroom with a Kyle, a Kaylie, a Kyla, a Kayla, a Mikayla. Hadley may only be moderately popular (though rising fast: from #921 in 2000 to #178 in 2011), but in a classroom with a Madison, an Addison, a Madelyn, an Adelyn, and a Hailey, she may feel more like a member of a Jennifer pack even if she doesn't have to use her surname initial---and a Haddie may feel like she belongs to a group of a million girls going by Maddy and Addy. '
I'd re-think your choices if you want something that sounds fresh and stands out a little. If you're not bothered about the names being very 2012 and blending in with tonnes of others that are very commonplace, that's fine - they are all very pretty choices, after all! Just name your daughter with your eyes open to the popularity of your picks and their sound-a-likes.
