Hm, haven't I seen this wall before?
Anyway, I like your vectors, I really do. ^_^ And your ideas are sweet and clean..
What this wall needs is to consider lighting, since it's a sort of scenic wall. Since it's night, she needs to
have shadows on her, with light on her either from the shooting star (possible?) or behind her. :) Same for the fence,
it's a bit flat..
Also, a tip for painting shooting stars on either GIMP or Photoshop; use the 'fade out' option and paint a
streak at the angle you want. Then smudge in that direction, using smudge at low opacity but keep the 'head'
of the star round. :3 Hope that works for you!
Good luck in walling!
