Saw the image above on the subreddit for the game and was inspired to edit it into the Isaac skin, my favorite for the Tec-9.
I remade and moved chunks to better match the official model, and decided to go with a shaded style without outlines for more depth. Just for fun I made a quick GIF out of it by flipping it upside down for a fake reflection, under a white gradient (I would have used alpha but that doesn't seem to be supported by the gif format) and some transparent lines like you see in Drift Stage, an upcoming retro indie title. I fooled around with the preview image as well so it wasn't boring.
I might do something fancier with the animation (like say make the stat-track numbers change), or I may even make some of my other favorite skins to go with it.
