The Angry Sun and Hammer Bro from Super Mario Maker 2

The way the Hammer Bro graphics are arranged doesn't really work well with the custom sprite. As you can see in the GIF below, the feet's animation is off, and since there's only one 16x16 tile for the sprite's upper part, the tip of his hand is always showing up, no matter what frame he's at.
You can probably fix the feet by mimicking the graphics arrangement of the graphics file that comes with the custom sprite. As for the upper part, the best possible solution is making so the sprite uses two tiles instead of one, like Eminus's waiting submission, Gijinka Hammer Bro, seems to be doing.
The Angry Sun is completely fine though. I feel like, however, you could've included a custom palette that makes his eyes blue for those who're looking for accuracy to SMM2. Feel free to resubmit the Angry Sun separately.
