You gotin alot better, but what you should do to make them even better is blend the render. Take the lasso tool draw around the whole render, then press layer mask at the bottom of the layers pallete (make sure the render is 1 layer). Also the backgrounds are still a little plain.
It worked fine for me... if the background on the render layer is transparent, then select all of the transparent pixels and right click and click select inverse, it should work fine.
lols you've fucking improved bare man.
they look tons better
but you need to read up on having everything to 'match'
if you get me.
but yeh good job, keep practising
