Opinion Required

Hi everyone,

My sister is in US and is due in aug. We are looking for girl names. We have these names in our list. Vinamra, Ameya, Akshara, Samaira. And unable to decide as we think of the pros and cons of these names.
Vinamra - Liked the named but seems its sounding too traditional
Ameya - seems this is unisex name
Akshara is bit old name. Samaira is new but reminds too much of name sameera. This is my opinion.

Whats your opinion. Which one do you prefer.
Also you can please suggest any other name.

Thanks in Advance
Anvita
