Editorial Illustration

I've never attempted editorial illustration before!

Some good examples that I want to take note of:

Humour,
Great characters, obvious message about greedy bankers,
Piggy bank doesn't really need the word 'bank', perhaps a coin slot or a penny would be obvious enough?
A limited colour palette would have made this image tighter. At the moment, the bankers seem a little out of place because they don't fit in with the colour scheme - perhaps what the illustrator intended- but I'd prefer it aesthetically if they were created in tones of pink, browns and greens to match with the piggy. The blue banker in particular just seems wrong, but this completely adds to the message.
I'm contradicting myself.
Really like the textures on the paper, a convention of editorial illustration. Why is this? Why do I expect it? Breaks up the simplistic blocks of colour? Cheap printing aesthetic?

Powerful, strong, bold.
Serious topic, communicated effectively.
Use of character without unnecessary information - we don't need to see her eyes or clothes, only that it is a woman, that she is shouting(?) and that she is raising her arm. Symbolic - statue of liberty, salute, rebellion, power, campaign.
Nice use of colours, ties the whole image together by sticking to a few chosen colours.
Texture again!
