Hey, nice to meet you too. So I don't have a general portfolio for sprite creation or anything but I made this game in about a week. Could definitely add more depth and more frames but was mostly working on mechanics: https://javasean.itch.io/survival-game
You can check out some of my websites darkcontraster.com for art but it mostly is my hand cut and digital collage art. javasean.com has a small web portfolio. If there is a particular type of art example you'd like to see though I have many things on my computer I can send to show.
