Oooh I love the shading on this! Everything just looks so soft, and the colors make the image feel so nostalgic and happy... plus the actual theme of the art is also pretty funny so that's bonus! The perspective is also really cool, how it kinda feels like it's fish eye (is that the right word?) due to how the ground behind Mario looks like it's a ball. The cluster of Goombas is also amazingly drawn, and I really like how you did the grass. Super awesome work, keep it up!!!
