You choose your own lawyer, and you and your lawyer choose your own trial strategy, so objecting to your lawyer's performance is almost never going to get you relief in a civil case (and can be problematic if it's a lawyer you chose and retained, yourself, even in a criminal case).

You have posted multiple threads asking basically the same question, but have not shared a factual context that would allow any sort of detailed or fact-based analysis. You have not shared why various things weren't done, what objections you made at the time either to your lawyer or the court, or what harm you suffered (if any). The answer to your question about getting a new trial, as stated to us, is "Probably not, go discuss your case in detail with a lawyer in your state."
