I love cats with poofy pants <3 I draw them too often ahahha Your page flow is really nice, it's easy to follow and I enjoy your color choice (it's simple but sometimes simple is better). Congrats on a well deserved DD!
The only problem is if you see this and haven't seen the pages before! This is awesome, and it's the first time I've seen a comic page selection as a DD! I didn't know they did that, but now I know why!
Did he kill the monster in one hit? Is it still alive? Looks like it might be dead!
Seiyuu-ka is a Chinese manga. The main character had to voice act a Tiger that looked just like your kitty. Matamune is a character from the Japanese manga Shaman King, who also looks like your charactar. Both of them have a fighting role at somepoint so I mistakened it to be fanart of one of them at first XD
