My first tip will be, to not stroke your render like that.
If it didn't blend to begin with, adding a black outline around it won't help anymore.
The smiley face just doesn't fit. Double focals like this usually don't work out.
Read some tutorials bro, google images/ tutorials. Deviant art, Sig tuts
Anywhere you can find something that you think you can take on.
Also..try not to make your text so big and slanting it like that is a no no.
