Well I took a little break from doing individual characters to do this. I kind of wanted to do this for a while so here it is.
I realize it has mistakes, but in general just tried to capture them as children.
As you can see, Usopp and Sanji are kind of shooting pachinko at Zoro's head (not his head just an apple). I decided to draw Vivi and Carue, too. Just because I believe she never stopped being a Nakama. Also Franky is trying to get Luffy off his tank xD. With Brook.. Since he was never shown as a kid, I included him as a former version of himself.
Please let me know what you think and feel free to check my gallery for other artwork, too.
