Harper - very pretty, just a bit common/trendy for me
Whitney - not a fan.
Tenley - Not a fan, but I like Tennille
Honor (I do not like Honora, sorry) - I have no problem with Honor
Ireland - seems contrived (like you're trying too hard)
River - pretty
Winter - pretty
Parker - dislike for a girl
Emery - love for a boy! This was my prom date's middle name! I think it's pretty for a girl, too, but there are so many other Em- names, that I think it's kind of unoriginal. Pretty though.
Allegra - it's nice, but now it just reminds me of the allergy medication
Mallory - I really dislike Mallory. No particular reason, I just don't like it.
Eden - Not a fan of this name. I prefer Eve.
Auden - I've only known little boys with this name, but if you don't mind unisex names then that's not a problem.
McKinley - HATE. I think Mc___ names as first names look so unbelievably trashy.
Harlow - very pretty. I like Harlow.
Odette - Really like!
Haven - meh. I don't usually like word names. Destiny, Haven, etc.
Laken - I LOOOOVE Laken. It's one of those names I won't use myself, but it's really pretty.
Blakelee? Blakeley? Blakely? Blakeleigh? - strongly dislike all of the above. The fact that you yourself don't have any idea how you'd spell it is a testament to how made-up it is.
My favorites for you (in this order) are Laken, Honor, Harlow, Odette.
