Jerry, you’ve got some interesting things here. You’ll draw remix attention with one simple but fundamental change—instead of uploading a full mix and calling it a sample, upload samples from your mix. Take that cool guitar, snip us a bit, and make that part of your upload. Take the other individual parts, and also make little wave files of samples of them. Upload your vocal as a separate a capella. With this approach, you may be able to “make it home” with a remixed track. Fully mixed tracks can be remixed, but they’re much less useful, and really not quite in the spirt of the thing. It is helpful, sometimes, for someone to upload stems, and then point to a place where the full track resides. But
it’s less helpful when you upload the fully mixed track.

I hope you’ll re-do these uploads, as there are some fun elements here. Uplaod a zip file of the instrumental pieces, and a separate
file of your vocal, and see if the fun begins.
