For the "where can I find love" one, try pulling the character above the grunge layer so he looks clean.
The blue sig is very busy... I find it difficult to focus on any of it. Also the styles of the different characters don't match; the creatures have a somewhat realistic look, then you have a flat shaded animé character in between them, and again another differently shaded character to the side. This makes for a very disjointed feel, as none of their styles fit together.
I like that you're experimenting with text styles, positions, and fonts. Keep it up.
