Am I posting too soon?

I've posted all three of my stories here right after writing them and then found errors after they were posted. I also know that I usually do a better job of editing and proofreading if I let something sit for a couple of weeks to get more distance from it. Are you seeing clumsy wording, missing words or other flaws consistently in the stories? I'm thinking of keeping any new stuff for awhile before posting. I'm asking for criticism here and I won't be offended by anything you say (well maybe if you get crude about it). I already know that I should have done more research first on the Trojan war stories. I know I got some names and relationships wrong in An Achean Tale. I'd like to hear any other suggestions.
