KH - Keyblade of Heart

This is not much. I wanted to post something bigger, but I'm in the middle of a depression right now. Anyway, as a fan of Kingdom Hearts, I always wondered how this Keyblade (the one created from the hearts of the 7 Princesses) would look like completed. So, this is my idea.  
 
What do you think?  
 
PD: I would like some comments in my previous pictures about "Zag Universe - Crossovers" and "Phineas and Ferb - Noirs Scene", please.
