What if I will clean/optimize/remade someones art?
For example I found a great SVG art which I like but it is really messy inside. My internal perfectionist tolds me that is bad and after several hours/days I will have a clean but identaclly looking piece of art.
Upload it as separate page with a link to original?
Contact admins so they will add to the original page a new file with info that it was optimized by me?
The same as above but contact to creator instead of admins?
P.S I don't know if I want to optimize someones art for now but have a question...
Yes, you could do this. As long as you listed the proper license and attribution, that would be ok.
No, admins would not add it to the original page because it is not solely a creation of the original author.
Yes. If the author decided to upload the new version to their submission, or if they gave permission for the new version to be added by admins, that would be ok.
