I love Nicola Scott's art but I don't know why for some reason she just doesn't seem like a fit for earth 2, I know people think different and i'm sorry but I think she is better fitted for a title like World's Finest or Catwoman(when Palmiotti starts writing WF) and to the main point; the artist's I think should take the reins:

KEN LASHEY

This guy is talented and I think he can handle Earth 2 better his art is not everyone's cup of tea(black hawks reviews) but it is very nice and I easily see him giving Alan Scott more constructs. His covers are outstanding and Yildiray Cinar is just not doing it good on Earth 2.

TOMAS GIORELLO

This guy is talented and he could also do some work in Earth 2 as you can see an Earth 2 issue he did above with other DC work. He has detail like David Finch without making it dark and he uses only pencils.

EDIT: CULLY HAMNER

He is the top New 52 designer, he is a fantastic artist and even helped develop Earth 2 designs and I know some people still want Nicola but c'mon.

SEAN MURPHY

"He is more suited for a dark title"I know some may say that but he has done lighter work so he can suit it perfectly.
