I like the realistic details in this picture.Deidara supposed to me younger but thats okay.His fice expression is quite manly than usual, this makes it original too.Also you drew Kuro very well, if it was was drawn by Masashi Kishimoto, I'm sure it would look like that.But in my opinion, you should draw more shy.Yes she is a brave girl but we can say without thinking she has special feelings for Deidara. Whatever, I like warm colours you chose.Thats 'an innocent and romantic pose with wild atmosphere.Their clothes are are a little big for them,eh ? That'a nice detail too.And I love the sunlight's angle. It's a lovely picture.You may never see Deidara like that again. Good job.
She is not related to Deidara. That is like saying Konohamaru is related to Naruto 'cuz he says nii-san (which translated to big brother). Like how Naruto says Sasuke is like his brother because the were so close. Kuro and Dei were on the same team like Naruto and Sasuke. So they probably have a brother/sister relationship.
I always thought that, in fact I posted long time ago a journal about this, but I really had doubts for a while, since I'm not reading manga lately, so I was like... maybe Kishimoto said that they are brother and sister?
I want a Kurotsuchi flashback pretty badly. I keep waiting for these newer characters from the non-konoha, non-suna villages to gain more of a following. Looks like I'm going to have to wait a bit longer.
