Wow, this is a really engaging illustration; you can really tell something horrible happened to the ship! Right away the lighting made a good impression.
Looking closer, I felt that a number of items lacked detail-- specifically those which are cast in the light. Nothing is reall missing, but i believe that certain items (the carpet, the inside of the chest lid, and the birdcage) would benefit from some very sparing details. Woodgrain, fabric lumpyness, consistent lines for the metal cage, etc.
Other than that I don't see that you would have much left before you could consider your work good to go! Kudos for illustrating 50 objects! You have a knack for balancing the weight of detail and value!
