Hey Fernando,
Thanks really like both logos, and the silhouettes are great, my only suggestions will be around trying other fonts and colours. On both logos try the silhouettes in just black or white, or try the girl in orange or pink while leaving the boy in blue.
#28 see if you can incorporate the tag line words.
#29 try different background color from green, and not sure on the position of the tag line words, maybe they can wrap around the bottom of the logo.
Hope this helps, thanks again
Cheers
Alan
