I think as a whole it's well done, not sure myself about the last page though as I don't know what's going on there and they might be confused by various random images with no words to explain. Personally I would either add more to explain it, or chuck that page altogether.
Good luck though mate, your work is great so hope you get something outta this.
In other news, I've started modelling a house today, using various technique's learned from books, internet and uni. When texturing, should I really be looking to make my own or is it okay to take brickwork, wood, etc from the internet? Especially if it's something your going to show in a portfolio like your own Asura.
