SG50 - from IZ's perspective

I asked IZ to draw SG50 related for his drawing class, but he refused. He said he'd draw one for me when we g to my brother's for SG50 makan.

So, at my brother's, he sat there, and started drawing these. 

There is (clockwise):

1. SG flag (albeit a star - not sure if it's cause of space constraint)
2. USS (the palace looking)
3. Merlion
4. Gun
5. Flats
6. Helicopter
7. People
8. Clock tower
9. Singapore Flyer

All these he drew from his own imagination
