SpaBel Rolling Girl - WIP - Which One?

Which one should I continue with?
The top one?
The bottom one?
I like the Top one better but it's ya'll's choice.

If you choose the bottom one, should I color it?
Should I leave it black-and-white?

Help?

This is all made on MS Paint because I don't have a tablet so SAI is kinda useless to me...

Btw, SpaBel id the pairing of SpainxBelgium from Hetalia

EDIT Thanks for everyone's input!! ^^ Sadly, I have given up on this though, sorry to dissapoint everyone...
