thats fan-art, not the official syringe just so everyone trying to scan the game version knows.
But it is beautiful work!
It would be a bit of a faux pas to put a link to your portfolio in a game. But as a way to watermark your fan-art as belonging to you its really cool! Every artist has seen their art get stolen and their watermarks get cut out for youtube thumbnails/ article images/ etc. So this is a great way to put your signature right on the image!
