Bit of an explanation behind this one. This picture partly stems from an old RP where Inkbrand was chosen as an "Element of Harmony" sort of thing, with his element being Justice, and also partly from a conversation I had with someone about "Alicornification" - specifically, what aspect of our characters, if any, could they potentially become an Alicorn paragon of.
From the very few examples in the show, ponies who are made into Alicorns (i.e. Twilight and Cadence) seem to exemplify intangible ideas, ideals, and traits, rather than tangible ones. My friend and I got to talking about what ideals our characters might exemplify to become Alicorns, which lead to this picture. Inkbrand is a very flawed character, but if there was any core value he might learn to be a paragon of, it'd probably be Justice. Inkbrand cares about what's fair and everypony being held to the same standards, but those feelings tend to be skewed by his own personal experiences instead of being unbiased.
I didn't draw the emblem of Inkbrand's cutie mark on the throne. It was drawn by a talented artist from a different website, for the aforementioned RP.
