Hatake Sakumo, Konoha's White Fang, and his son, Kakashi.
I've developed a real soft spot for these two. The idea of serious little Kakashi trailing after and worshiping his father is way too adorable to me. Of course, by the age he is depicted above, Kakashi probably would have already been a chuunin or something, busy fighting his own battles...but heck, artistic license ftw, hee.
Tried experimenting with a different color style on this one, and I think it turned out well.
Done with OC3.
