I agree, you really should blend in the render in the second one. And the chick in the first one looks cool, but the colors...
i also agree that the second one looks kinda plain and it makes the render pop out so much more but good job and keep it up
try and ad more colors and brushing the text is good but you could make them interact with quotes or vector or combined there both nice 8/10 the second one needs more color and blendin of the render
