Well, I thought I could totally redo this assignment... But turns out I couldn't.
I wanted to create a postcard which has traditional toys on it, to remind people of these forgotten toys. I chose 3 simple toys, which were the Chateh* (The toy with lots of feathers that you kick around), Chinese Toy Drum and the Indian Top. This is the original 8 postcards I had.

After that, I received comments the rope wasn't very obvious, and that I could use the rope to form words rather than just letting it lie around randomly on the postcard. I tried to create a rope from a tutorial... But I couldn't get it to work due to it being for different programs. x_x Sigh.
I tried another method, which wasn't a realistic look but at least it's not as bad as the 1st. Also, I added shadows to the bottom of all the objects to give it some depth. Here's the final colour sets.

Postcard 1 (Neutral)

Postcard 2 (Army Camo)

Postcard 3 (Chill)

Postcard 4 (Warm)

Postcard 5 (Speaking colours)

Postcard 6 (Shouting Colours)

Postcard 7 (BRIGHT NEON!)

Postcard 8 (Dull)
Postcards 5 and 6 share the same background, since I wanted to try out different colours sets. In 5, the colours were "Speaking colours" while 6 had "Shouting colours".
This is the back of the postcard. I kept it simple, with a continuation of the rope trailing around the back to act as a border between the text and address section.

Postcard Back
I'll be going with the "Speaking colours" design (Postcard 5) as the final choice.
The reasons being:
Postcard 1 - Also acceptable, but I didn't want a a drawing of something in the natural colours, if I did, I rather get a photo of it.
Postcard 2 - The colours are quite nice, however, I think the colours blend too much into each other.
Postcard 3 - Chill is nice, but it's abit too boring since it's mostly focused on the blue series.
Postcard 4 - Warm suffers from the same reasons as Chill.
Postcard 6 - While 6 and 5 share the same colours, I didn't choose 6 since the colours clashed with each other and fought for attention.
Postcard 7 - BRIGHT NEON is too bright for a postcard. I don't think people would be able to look at it for too long...
Postcard 8 - Dull is too dark, and so it's abit hard to see details. Also, it's quite dreary for a postcard.
