How do I make pixel art look good?

So, I have this sprite:

This looks correct, it also looks correct on the editor view, and you can see my display settings (full-screen integer scale, low quality full-screen, sampling nearest):

But when the game runs, regardless of the windows size, look at the fish now, the white line has increased twice in size. How can I fix this? I've played with the display settings and used every permutation, but nothing fixes it.

Thanks!

I think your rez, and the screen rez don't match.

Try F11.

Nope, in fullscreen mode the problem still persists.

I notice it doesn't have any padding.

Try the button next to the resize button in the image editor.

Made no difference :(

Making it 14x14 fixed it. So every pixel art sprite has to have an even number dimension? Well, you learn something new every day...

I don't know the reason behind it, but I've had the same "pixel drag" problems in photoshop and construct when dealing with non-integer coordinates and odd number sizes. It might our GPU drivers, rather than a software problem. Anyway, great to hear it worked out for you! Your game looks gorgeous!
