Not too bad, however, 3 things:
1) i don't like the "grey bits" i think you should have blended them in nicely as a transparency gradient.
2) loose the black borders, im a real enemy of borders, i only use them on the odd occasion, cuz well, it looks better without them.
3) crosses/+ sings, are, far too big, not to mentioned overused
, i think if you made them about 50% the size they are, and instead of using them on overlay mode which it looks like you've done, just smack the opacity down to about 30%
that way it maintains a "creamy white" look.
and yeah.
overall not too bad, keep it up.
oh, one last thing, i don't think the text fits, it stands out too much, blend it more.
(and don't put huge "by me" or copyright lines, it just messes em up)
the best way to do that, is to blend it, (in a small, say 10px font), and blend it somewhere, where it can only be seen if you were looking for it.
and yeah
