Your first 3 shots had some nice touches but your signature is, sorry to say this, quite hideous. Something simple and subtle often works best. And really, it shouldn't be splashed right across your photo. It really ruins it.
Got to agree with Kman - didn't even look at the photos, too distracted by the truly awful borders and signatures. If you are going to do a border (personally I don't like to) then it has to be subtle. Same with the sig.
