Illustrative vector art on newgrounds? pretty rare stuff these days.
i would recommend vastly sizing down your images, as looking at this full screen at 3413x1920 vastly outstrips normal monitors capacity to see the image. unless theres some extraordinary detail in the image theres probably no reason to render it beyond 1200 px eh?
the figure is well crafted, but the composition is uneven, and the same effort that went into the figure is not there in the background curves, as well as it being cropped out awkwardly on one side leading to one flat edge when all the rest are curved.
