Stuck! Sketches April 15

Yay, I have finally managed to get both sketches done in the one month. The time always seems to slip away before I get to one or the other.
My ten year old Ben is mad on Nerf guns. He loves using me as target practice from time to time. Litte cheeky ****! He also likes to modify his Nerfs making them faster to load and to shoot harder. Ouch! He's been warned to only shoot at the walls etc.
