Can someone help me with this?

I've finally made Silvia's Enchantix wings!!!!
The outfit's ready,too.

Fact is,I wanted to ask for help and opinion:
1)Do you think the wings look okay?
2)Are they in proportion?
3)Do they look like Enchatix wings?
4)Are they her style?She's a fairy of future...what I'm asking is:Do the designs suit her power?

Now for the help:
Colours!No idea at all.Her favorite colour's purple but these many things....Help me with it,please.Props for anyone who suggests a couple of colours.
