On these extended sides I selected the face I wanted to extend and hit the G key on my keyboard to go to the extrude tool. I then used the re-size tool to move the face of the new cube inwards and used the move tool to pull it outwards from the rest of the object. This resulted in wings. 

On the two faces that are on either side of the main front compartment, I used the same technique but used the move object tool to push them further inwards. This was also done on the back to create ducts for the engine to fire out. 

Front of ship

 I added more to the back of the spaceship to make it longer and roomier, and added another section to the top, tilting it so it looks like a screen window.

Reflections

I'm a lot happier with this design than my first attempt in class. Hopefully tomorrow I can maybe add a bit more to the design and colour / texture it as well. It was nice not having to learn things under pressure and just relax and have fun with the model. It's made me feel a lot more confident with how tomorrow will go and hopefully I'm on the right track with learning the software. It's been a hard process so far, but I am dedicated to trying as hard as I can to be alright at it!
