How do I go about making this simple image better?

Sorry, not sure if this is the right.. anything. It's my first time here and I'm just looking to improve this picture.

I do quite a few simple things on photoshop but I have no idea how to go about making such an image look less rough. Many things I want to use it for, awesome if anyone could fix it or tell me how I would go about doing so myself.

Thanks you very much for all and any interest.

It's best done with vectors and since most beginners have a hard time with them, I've done it for you. The PSD is also attached below the image, in case you want to make a modification.

Note that I only drew one half and mirrored the other.

That could not be more perfect, thank you so so so much.

Cool you can "thank" people here, that's so much better than any goddamn upvote/downvote thumbs up/down system.

Thank you Furio.

Thurio.
