Hi Akina. Sounds like an interesting project, but my concern is that your title sounds rather demanding. In general, length until the request substitutes for politeness in English so I think better alternatives would be "Would appreciate your feedback on something I'm working on." or "Would like feedback on a project of mine." The word "want" is also rather forceful for someone who is soliciting other people's help. Just cultural tips.

I know we encourage a culture of straightforwardness on this site, but in my experience even people who say they want succinctness still get offended and/or take the wrong meaning away from direct statements.
