SOTW stuff, haven't done this type of tag in a while so I followed loosely a tutorial and then added some stuff.
Very nice! The colours are so different, yet they all seem to compliment each other I like the 1st one better, I just think the border on the second one is a bit too thick. Still, great job on this!
I'm not a huge fan of portrait signatures but I like these, the lighting is very nice and the colours look lovely all together. I have to agree though, the border on the second one is too thick but I do think it would look better with a border, just maybe a thinner one. My main critism of the whole piece has to be I thnik the render should just be blended in a bit more, like maybe a bit of blurring near the edge of the legs, I just feel he doesn't mix completely into the background. However I do think these are really good, well done.
I think the blending is fine, at least for this kind of tag. The lighting is also pretty good. For a portrait tag, this is pretty good. The smudging in the back is pretty amazing.
