The design looks elegant, I liked the idea, and the choice of colors and their reflection inspired the Japanese anime in the 1990s, like Girls und Panzer.
What I didn't understand is why is there a mouse at the bottom of the image? I thought it was an indication of corruption, but the content of the photo did not show wasted foods or such details.
Glad you like the design, I haven't watched Girl und Panzed but I can see how you could make the connection. I summarized the idea in the OP but I'll take this opportunity to explain a bit more for anyone interested as I love talking about the layers of symbolism.
The idea originated around the recent Bitcoin halving (May 2020) and the current state of the global financial system. I drew my influences from the soviet constructivism style that was (in the 1920's) used as a 'call-to-action' for the common-man to unite and build something greater.
I'm also inspired by Lucho Poletti's interpretations of pinup poster propaganda art with a bitcoin twist and I would like to think that a lot of my upcoming work parallel's his to a small degree.
Starting from the bottom up we have the numerous piles of dirty money, dollars, euros, pounds and yuan with the rats (as @krogoth pointed out) symbolizing filth - bags upon bags, thanks to endless quantitative easing.
Next up we have the human barricade, made up of what seem to be riot police. Upon closer inspection the name plates reveal that these are some of the better-know instigators of financial terrorism and public denouncers of Bitcoin. This line symbolizes the small minority, both state and private, who are the gate keepers to, and rule makers of, the current financial system. I wont spoil it by listing out the names but it shouldn't be too hard to interpret. As an added bonus there 2 references to 'Money printer go Brrr' and one to the 0.1%
Above the riot line we have the tanks which are no particular model but a composite of different tanks throughout military history. The main tank does indeed take elements from the Challenger 2 so well spotted
This line is meant to represent the monopoly on violence held by 'the state' which is the only thing that gives fiat money any assurance. If you loose the 'Fiat Army' you loose the fiat.
Moving up from there we have a fictional skyline made up of prominent banks and financial buildings from around the world. Some more recognizable than others but all equally involved in financial plunder and corruption. And above the concrete jungle we have, and this is my personal favorite, helicopter money!
Rising about this collections of filth and financial corruption we see bitcoin as the sun (similar to Mao-era posters from the 1960's). Bitcoin is a fresh new system, shining a light on the draconian ways of the old one.
Hope that helps
