I made this new sig in about an hour and a half, I tried some new things with c4ds and would really like to know what you think about it.
I few things that need to be improved here; Center your focal more, currently it is too far off to the side. This leaves quite a bit of empty space, with little focal. Your background has little unity; the left and right do not blend with eachother, the left doesn't blend with the dino. Try using gradient maps for color consistency. In terms of style, the effects obscure the main dino's body almost completely, and then when it bleeds over to the left, it becomes less opaque allowing you to see some background dinos. This is just something which breaks consistency (which is important). Make sure you work with high quality stocks (if googling images choose the large image filter), and work on a high PPi (pixels per inch), default is 72, I always work on 300+, as your dino looks a little bit low quality, though this can also partially be remedied by use of sharpening (though be careful not to oversharpen). I notice you didn't even try to get lighting set up, but I find that good lighting vastly improves the quality of a signature.
