[MENTION=20005]Matthan[/MENTION]'s advice is the best I see here. Your ad, as it stands, is very generic. To follow that up with a bunch of restrictions could definitely play as a turn-off, even for players who might otherwise fit your play-style. Having read a lot of pitches for campaigns on Roll20 and similar, I've found that the best ads are the ones that pitch a specific kind of game, with the restrictions, alternate rules and house-rules that are put in place to support that.
I imagine two very different pitches:
"We like to play a stripped down game, with simpler mechanical options, because we find it focuses the attention on at the table creativity and story-telling, as opposed to carefully constructed character builds." (Some people will find that appealing and some will pass.)
"I like to run a my-way-or-the-highway game, so I've restricted most of the mechanical options from chapters of the PHB that I can't be bothered to read, and if you bring any ideas you got from anywhere else, I will definitely not be allowing those at MY table." (I think most people would pass on this, though I guess a case could be made...)
I think it's also great to note that you are building off a playstyle that you've reached with other players in your group. In my mind, that is a good sign, because it indicates that you are able to work with players to find a game you all want to play, as opposed to deciding unilaterally about a very specific game you want and looking for players who are willing to subject themselves to your personalized version of D&D.
