Does it need much of one? I suppose my photos could be more cohesive but my style is evolving and I can't keep reshooting everything. So what I have done is to use the gallery re-arranging feature to move things around so that the look is less chaotic and I think that's done the trick.
I would value your opinion but so far consensus from folks who have looked have been positive.
What else can I do? Or should I do? Changes ought to be allowed to take effect but sometimes it can be obvious pretty quickly if a particular change was not so good an idea...
