Honestly, there’s nothing to complain about here. I really think both graphics are stuning! However, for your “Mintys Cafe” graphic, I think a gradient or striped background would give it a bit more pop. Apart from that, really nice!
I don’t really think people who want GFX would want an asset not created by the one they commissioned. I know I wouldn’t. I would also suggest you add that you add this to the top of your post to let those who would commission you that you didn’t create the icons.
