Try to get rid a bit of the aliasing. Is it better?
Not really. Actually if this image were high res, aliasing would not matter much, if it scales down, that will smooth things out (assuming your monitor size is smaller). You can try to upscale this image by a very small fraction in waifu2x like --scale-ratio 1.05 (without de-noise) and see if that helps. I've never done this myself, so might actually go and try.
Edit: I am also assuming that there is anti-alias sampling going on when scaling down.

Compared to the original I'd say it's quite a bit better.
So I decided to experiment a bit and here is my version of this image.
Which has close to none aliasing now.
Things I did:
waifu2x upscale 1.5 with 0 noise (not really required, but I just wanted it)
Run the image through edge detection algorithm.
Once you are happy with what the colors look like select by color to get only the edges on the image.
Run denoise function of your image editor only on the selected edges, adjust the strength of such.
Conclusion: So cheap method is pretty good, the edge detection is required because if you try to denoise the whole image, the important colors will get smudged and loose contrast. This all comes down to how well you can figure out the important parts of the image. For this example I spent 5 minutes, so obviously it could be even better if you manually check things that were selected. Hopefully you find this information useful.

I'd delete it for being upscaled tbh. We're really only supposed to do that with images below 1000x700 OR images that are borderline and would benefit from it.
Do you think a 1920x1080 version would fit this picture better then? or would that stretch out the picture too much?otaku_emmy said:

True, I would probably not upload upscaled when there is no need for it.otaku_emmy said:

If you're actually talking about resizing the image without maintaining the AR of the content, then that is something we don't allow (except in very rare cases where the artist apparently messed up). See section 14 on the Image Quality Evaluation page.PrimalAgony said:

If that's not what you meant, then please clarify.

Though what i most likely trying to find out is what kind of image size is allowed.
I think we have images (or at least one) over...12000 pixels wide so it gets up there. Basically so long as something isn't square or below 1000x700 it's got a good chance of being alright.PrimalAgony said:

A trick I was taught was to use the resolution "bar" below the images in the index as a cut-off point. If the image overlaps that, issa no good.
Though for an uploader, that method would require uploading the image before checking if it's acceptable to upload...otaku_emmy said:

Just read through the Image Quality Evaluation page and Upload Guidelines. That should always be done before uploading anyway. That should give you all the information you need.
What about 4:3 displays though?otaku_emmy said:

Is that too square or no?
Unbelievably, 4:3 monitors still exist out there, so this is fine. A square would be anything less than 5:4 basically.Upload Guidelines:
Minimum Resolutions:
By standard aspect ratios, an image should be equal to or larger than:
- 1024x768 pixels (4:3 Ratio) or
- 1280x720 pixels (16:9 Ratio)
