I enjoyed this piece, keep writing! Now, of course it's your choice, but you might consider shifting the wording of this slightly:

>may your face meet's not a poser,

into this:

>may your face 
meet not a poser's

which is what I think you meant to say :-)

Oh yeah, and the centering issue can be caused by a few different things. The most often, I find, is not ending your tags cleanly. Always start a new center tag for each part: so it should be

`<center><h3>what more?</h3>
by @franciferrer</center>`

(make sure the tags are exactly in that order. if they are `<h3><center></h3></center>` it will mess things up.)

and then put your image. If you need to re-center your image, put new `<center>` and `</center>` before and after the image.
