i agree almost all fo these are overshaprned. Just go to the layer you sharpened them on and lower the opacity, until you don't see the pixels XD.

You have some cool tags up there. Your best is probabaly the first two. Second ebign the ebst IMO. The effects go pretty well and the colors are ncie. But watch out for that gaussian blur set to..Uh i think it's vivid light? That effect should be used with extreme moderation, like most effects in GFX.

The others you should try to work on your blendind, And setting up the BG.
