OK so I will be working on the last sigie I wanted a critique on later I forgot to save an unflattened file of it but here's another one I've recently made. I kind of like the way it came out though I'm a bit tempted to crop it down a bit. I just went or something a bit easier this time I masked out the background and added another image over top of that and played around with the opacity a bit and this is what came out.

The composition is ok, but, there's the problem with the opacity of the image, it gets lost in the signature, as if the texture and the fonts are more important and i think the who thing together is important.

So my tip is duplicate the image and get it on top of the texture and play again with the opacities to one that works better and pop up in the image (i think multiply is a good option, bu it could not work too xD).

And another thing, it looks like you cut the image from its original background, and if you did cut the image /insert virtual high five/ you did an excellent job  it looks really good!!
