Love the fish! Are you planning on adding spec/gloss or keeping it diffuse only? some tighter highlights could help define the wetness of the fish/roe subbed! :)
Yeah, Darkmag07 is right. If you do use normal maps, don't have any high frequency detail in it. For the bricks, the most I'd use would be the brick shape and that's it. You don't really need all that extra normal detail imo. The diffuse takes care of that. As for image hosts, I'd say dropbox but unfortunately it's blocked…
@sybrix: I might try working out a timeline. I did one before when I wanted to do the HMS Victory using Excell spreadsheets. Our time management class has us doing mind maps for our demo reel projects. I'm not a huge fan of them though. I like to write notes on my ipod before bed to tell myself what to get done the next…
