Love the first one! (Luv Naruto <3) Second is a bit oversharpened imo, but you did a great job. P.S: Do you mind pming me that 1st Render? Thanks.
Yeah 1st one looks great, more of the bright c4d tho and its pwnage. 2nd needs stronger lighting imo.
1st mid to right is awesome, rest lacks because it's too bright and messy on colors, kills the mood 2nd BG looks nice but the blending isn't all that great.
i like th top one coz theres more flow and theres better depth int hat sig..It looks nuch better, some effects could be sharpend a lil more thought but overall its good. The bottom one is a okay bowever i think some smudhing could hve had more flow...actually looking at it doesnt look to bad,
