Big congrats to you!
And I'm going to guess along with others that you probably did better than you thought. My checkride wasn't particularly pretty either, especially my partial panel approach which I had done a LOT better during the checkride prep. And I nearly fired my DPE in the middle of flying the ILS when he started hounding me with questions about a piece of non-installed equipment, and then ramped up the harrassment when I told him I needed sterile cockpit at this point. During the debrief he said that the way I handled a glitch with my HSI was "worth 100 points" and that he had no reservations about signing me off. Unless your DPE said you just barely squeaked by or something like that, I wouldn't second guess him.
Whether you're ready to shoot approaches to minimums in actual IMC or not is something you, and your CFI, are better qualified to judge than anyone here. If you were well prepared, you probably won't ever be more proficient than you are now. My first solo in actual was a week after the ride. There is nothing like getting the ticket wet ASAP -- as long as you feel confident and safe.
