I think the top edge flows well IMO - but it's your guitar so you need to be happy. But if you stick with it, or something very close to it, I would suggest moving the marked-up pickguard screw hole to somewhere nearer where I've indicated. You've put it in a place with very little material around it, so it's very likely to crack. Also I feel that that top rounded corner would otherwise tend to lift over time and you'd end up with a gap which you'd notice when playing.
