Welcome to the Forum, Liuxi!
I am sorry that there have been no answers to your post yet, but let's hope that some of the many TIMES modeling experts will respond. My personal feeling is that you have probably not made any bad mistakes at all, but the model may just need further fine-tuning to make it behave more realistically, like it is almost always the case with new models.
