Shinachiku and Kasumi - NaruSaku Children

A fanart I've been working on for some time, a drawing of LadyGT's Kasumi Uzumaki and Dattebae's Shinachiku Uzumaki.
I thought of posting the uncolored lineart here so that anyone who wants to can color it.

BTW, if you color it, don't forget to show it to me.

Edit 02/28/2015: I forgot to post this here before (like, long before) but I fixed the lineart a bit.
Now Kasumi is wearing sandals, like she should.

Edit 04/03/2015: I had forgotten to draw the sewing on Kasumi's shirt. Now it's fixed.

Edit 04/03/2015 (2): Added more fixes which I thought were necessary.
