Oh wow! This is quite possibly one of my favourite pieces of yours! I absolutely love how fresh the colours look. The simplicity of it all is astounding. Supergirl looks really cute here and I love how she looks like a regular teen girl. From the winking expression to the nonchalant knuckle cracking, Supergirl is represented more fairly here. It's a nice change to the usual fare for most superheroines. I also really like the slightly blurred background... the downed robots (?) and the Times Square (right?) look great.
