Need Opinions Please

I need your help, oh readers (all three of you...). I have decided I need to do a ruthless winnow of my Tiles collection (these are "tile" images I've made myself) and only keep the very best ones, and toss out the boring ones (except the ones which are actually being used, like on my website, of course). So I beg you to go take a look, and opine about at least one tile that should be tossed, and one that shouldn't be (so as to save the worthy, if any).

Thank you for your attention.
