The last smudge one isn't too bad. If you wan't to make tags that are purely smudge, you've got to remember that your focal is very important, a long with depth and lighting, (since the tag is based on smudging).
Also text placement is always important. Look up the rule of thirds for that. Don't just slap on text into the corners, never looks good
also the one you're using in your sig is good, I like the text you used... Probably wouldn't have worked with any other text
