There all well executed, the tops a bit generic looking though, the seconds alot better, but I prefer the third the most.
The use patterns & lighting gives it a stronger finish.
The tags not strong but its not weak either, it works but nothing about its really grabs your attention.
You should try and have a go a illustraiting a tag, and then taking it to ps, instead of going about the same old routine as everyone else. I think that approach would more suit your style, if your drawings are up to that standerd then tagging should be a walk in the park really.
