He is ready to play dodgeball

Raaawh?! Rus ready to rough house?! And so am I!

RU is trying to take the camera away from the photographer for some reason. Great work, Keep going!

Hands are difficult to draw because of all the objects in them. There's no doubt about that. Your fingers are mostly correct, except for RU's left third through fifth fingers and RU's right fifth finger.
I'm not very experienced in art , but I've found resources over a few years. Take a look at Burne Hogarth's book , called "Dynamic Hands." Burne suggests something like a Nike swoosh so that the ends of the fingers fit inside a Nike swhoosh as action lines.
His book had helped me figure out hands in dynamic poses. I am sure that you will find something useful in the book "Dynamic Hands."

so now is that angry or playful? that's big thing I think.

wow....who does your claws these look very well maintained. :3

d'awwww Ru attacking

Strong JoJo vibe heh

Maybe RU doesn’t like the stuffed animal?

Whatever I said to make him mad, sorry ^_^;

He do got the claws tho to make sure intruders go bye bye! Really dynamic pose, too.

Woah, that's pretty cool ^^
