I don't really like the idea of putting both Haruka and Serena into a competition unless it's a friendly competition or anything Pokemon related. I support both SatoHaru and SatoSere and as much as possible, I don't bring up any situation or case that would place the other ship into a disadvantage or bad image. If I comment on SatoHaru, I don't think of what will happen on Serena's case or side. The same applies with my artworks. When I draw a SatoHaru/SatoSere artwork, I don't include any other characters in it unless they will not affect the ship. When I made that artwork that you've seen above, it's just plain ol' Haruka getting pushed on Satoshi's arms situation that I had in mind. I never thought of "what would Serena feel?". The same goes with the SatoSere artwork at my signature. I never thought of "What would Haruka feel?".
And I don't really like the idea of pairing Serena with Citron. Not that I hate Citron or anything but I just don't like the idea. At least, if I were to pair Haruka with Satoshi, I'd pair Serena with Calem or Shigeru or maybe even Alan. Sorry I just felt like saying it.
Long story short, if I were to discuss or make artworks for SatoHaru, I disregard SatoSere for a moment (pretend as if it doesn't exist) and focus more on SatoHaru. Same goes with SatoSere.
Sorry for my personal opinion post but I just felt like sharing it. Anyway, going back to the contest. With the remake coming, the contest really has a huge chance of being brought up as well in the show. Even Haruka has a huge chance of going back. I just hope they do not replace her in the game like what they've done in HG & SS replacing Kris with Kotone.
