I thought this was a pretty funny picture. It mostly works because it deconstructs the idea of learning instructions in video games. It just doesn't make any sense for a lot of this stuff to happen in those games. I haven't even played that many games that have made fun of that aspect. I think the little chicken is cute. I do think that you used a bit too much negative space.
It could have used more detail. It still indeed accomplishes what it sets out to do. I also like the way the little words are written in the lower hand corner of the picture. It might have used some color, most Castle Crashers fan art has color anyway. I guess we could add the gray knight.
