Eva just released a fantastic, grungy, music themed kit called Roxy. She is offering it on SUPER SALE through 5/31 - the GIGANTIC kit is only $2.79!! She also has coordinating alphas available on sale for $1.74. You can view the kit and pick it up HERE and the alphas are HERE.
My page is very girlie but there are plenty of blue elements you can use for boys in the kit!
