Ms Sin Ai gave me a tip on how to make it so I did make a few errors but in the end I get the subtraction part to look exactly like how I wanted. It was frustrating having to redo so many parts but the final look was worth it.

The final model 80% done

When the model was almost finished, I then think again like how do I make it more interesting rather than just pasting everything together. So I have decided to make some of them dangle away from the 'colony'. 

And now the final model is finished! I managed to make the model as how I imagined it in the first and I was quite proud of myself for being able to accomplish it. To be honest, I had a lot of doubts about myself as I'm not as talented as my other classmates and I am rather slow in terms of progress but I managed to accomplish this work on time and learned a lot as well. Also I am very thankful to have three lecturers to help guide me throughout the whole assignment.
