theyre all much better than your first one, youre really getting good at it :)
just some small stuff to correct, by sig:
reading/ireland - nothing really :)
everton - amazing sig, except for his left arm, which is too transpaprent, look at james' tutorial on makign good renders, most of that can be applied here (except for the extra copy to the side)
indonesia - left render the cutting isnt that good but thats probably because the pics werent that good, but again, if you cant show the whole body, then cut him off with an edge
also the logo is a bit blurry but you cant really fault that, there arent that many high quality ones out there
lucas leiva - again good sig, the gradient has to be a bit more gradual (drag across the whole length of the sig), and the logo looks too narrow, when resizing hold down the shift key and it will keep the same ratio
wolves - very good, one of your best surely, good job
very good job overall, especially since youre just starting, good luck and hopefully you will keep improving
