Hi Thomas, thanks for the kind words. Sorry, I do not have instructions for the shark though I remember it had 'Part 30414 Brick, Modified 1 x 4 with 4 Studs on One Side' in the centre to get the symmetric shape.
Why does this have so few views and ILI? This is pretty cool. Everything here fits together really well, and though the colour scheme isn't normal for buildings - it completely fits the game genre! Awesome build! ~Thoy
