Help with these sprites.

This is my first free hand sprite, so it looks terrible.
If you want to edit it feel free.

These are my first two sprites from scratch, any suggestions.

Please keep in mind that you can edit posts. Generally speaking, if it's been within two days, you should avoid double posting. Also be aware that you need to post your actual art here, not link it to an outside source.

Okay. Thanks. I'll remove the link.

This is my next sprite Sploosh

The biggest problems i see right now is that your colors are a bit oversaturated right now (try picking some less saturated colors. Looks at other sprites and study what colors they are picking, you can just look what they use and try using the same)
Also try adding additional darker/lighter colors to add some shading.

Don't be discouraged if it doesn't look good from the start, it is normal that it takes really long to become good at art. You just need to stay motivated and keep practicing. Also doing tutorials helps a lot. Here is some to get started: https://lospec.com/pixel-art-where-to-start

Thanks for the tips Ill be sure to try them out.
