Good, but in terms of functionality, (if it is, in fact, Soviet or Communist related) it's null. Celestia, being a monarch, could not gain support of a Communist group, as a monarch is seen as a head of a centralised state, whereas Communism calls for the absence of a centralised state. If it's Socialist, then it would indeed be politically correct.
I'd like to thank you so much for making this image! I am a democratic-socialist myself and have a bit of an old nostalgic indulgence for the old 'socialist-realist' images like those ones even if I was by no means a 'political supporter' of old Soviet Union after Stalin took over or North Korea today. Being I'm also a brony I got this image printed on a T-shirt and wore it yesterday at my local brony meet up and then continued to wear it that evening when I attending a film night with some comrades to watch a film about the Russian Revolution
