Re-Writes

I am about to re-write 2 stories for People's Friend, which have come back to me (very promptly again-1 week). I have a good feeling about one story, which was one of those which just seemed to flow, obviously it's not flowing in the right direction as yet, but I don't want to give up on it. Having said that, I do get that sinking feeling when I get a reply such as '..the storyline was too weak to sustain the reader's interest...' It's hard not to feel a bit down, but I suppose they know exactly what they're after, whereas I'm just going for a best guess, based on the other published stories in the mag. I'm just not getting it quite right. I need to keep the overall feel, whilst adding a bit more intrigue if possible... I hope that's the case anyway and if I keep trying I'll manage another hit with them. The other story had more of a comment, saying that the ending was lovely, but the beginning was a bit down-beat. In this case, that's really helpful to me, just perk up the beginning!
I think I might give Woman's Weekly a go again, I've got a story that's had some nice comments from various mags, but it's a bit unusual, I wonder if WW might go for it? I've never had anything more than a standard reply from them, but I know their stories vary a lot, so it might be worth a try?
