I'm of the view that those of us below about 2200 OTB or so don't have a style - we're rated where we are because of significant gaps in our abilities and knowledge.
We might be more comfortable in open positions or in closed positions or engaging in piece play or whatever, but that comfort level isn't about style so much as it is about where are knowledge gaps are smallest.
To have a "style" you have to have sufficient knowledge and experience where you can approach a game from multiple tacts -- choosing to play positionally, or tactically, or goign for complications or whatever -- and your choice is guided not by your limitations but by your conscious decision to engage in that type of play because that most closely aligns to how you think about chess.
Just my humble patzer opinion anyway.
I've read many times one needs to identify their playing style. I think I know what that means but I am unsure on how to go about. Please help. Thanks
