if you're looking for feedback and/or suggestion... could i suggest a SSB Zero Suit Samus? Your Samus looks and play pretty awesome to me (i have it in a mugen comp with Odb718's Samus) so a Zero suit one could be fantastic.
In the other side, have you test dragon792's TLOZ 3D Link?
For now, i won't add characters like Peach, ZSS, Yoshi, Captain Falcon, etc. Only main character and main antagonist of those franchises. Then i will start adding less important characters and characters from other franchises.
Wario and ROB - no, not in this version. Dedede - maybe yes. I still didn't really decided which Kirby "villain" (Meta Knight or Dedede) will be used. Meta Knight has cape, so, he will require more time, but Dedede is a big villain and we already have few.
