Design Clarity and Changes

Upon receiving  feedback on my initial dissertation proposal I have decided to make the following changes:

• The will now be 1st person. Although i still feel that a 3rd person camera would create a better aesthetic atmosphere, the player will become more immersed in gameplay from a 1st person viewpoint. In my feedback there were worries that i was undertaking too much with this project. By having the game 1st person  it cuts out 3d modelling the main character and animating the character. i will also save time on having to code a 3rd person camera in unity as a 1st person character controller is built in. 
• As i am creating quite a large environment that will be made of up of a variety of asset, it was also pointed out that this will be a large undertaking in the time frame i have. to solve this i have decided that i will make some of the assets myself, but i will largely source 3rd party assets from websites like http://thefree3dmodels.com/stuff/furniture/leather_chair/12-1-0-3560. this will cut the work load down considerably. this allows me alot more time to iterate gameplay and implement new features if necessary.    
• My project timeline is a bit vague on what tasks i will be undertaking during each sprint. i have decided to completely revise this.I need to refine my project timeline into 1/2 week sprints so i can break down the workload into tasks so i stay on track. I dont want to fall behind in development because my timeline is unspecified. i could easily fall into the trap of thinking 'i have time...'  just because I haven't set myself consistent milestones to keep myself disciplined and on track.
