Here are some close-ups from my Shippuden piece so you can see the details a bit better. I'm that idiot artist who puts way too much detail in small places where it isn't likely to be seen, but I think it adds a depth to the overall piece that's appreciated even if the small stuff isn't noticed.
I'm particularly happy with things like Gaara's sand, Kakuzu's mask design, Rock Lee's intensity, Ino's everything, Akamaru's fur, Hinata's adorableness, and the gloomy Uchiha corner. And I feel like I got the right balance of Naruto's sweet boyishness and determined young manliness. I dunno, I'm really happy with this and that doesn't happen often so I'm trying to enjoy it.
