Nowadays, It's probably best to make a reel focusing on what you want to get a job doing. If you want to do "everything", which is what you're demo reel is saying, you most likely won't attract much attention. If you want to show off models/textures, which is probably your strongest area right now, i'd do a turn-table style reel just showing those models that you're most proud of. So again, it depends what you want to do. If you want to be an animator, get some good rigs from creativecrash.com or 11secondclub.com and not worry about modeling and texturing your own stuff. If you want to be a modeler/texture artist, don't worry about the animation side of things. Keep going!
