The flow is bad. The last one needs to be totally b&W but that one isnt the best. I guess the third one would be the best.
It's kind of monotone in means of color and effects. It's just boring I guess. Also the right side where you did the whole cut-off repasted look just kinda kills it even more. That style never really looked all that great, atleast to me.
The only good one here is the B&W one just because it actually kinda blends, the rest are way to monotoned and no blending. like others have said just looks like you took a background and stuck a render on it "/
but kiu bro i have seen your other work and i know you can do way better
The third one is the best imo.
The character doesn't blend well with the background, play around with the contrast and find a color that will blend in well with the background.
The small light on the right of his shoulder is kind of not looking good in my eyes, but that's just me.
Though, the tag looks awesome. Good job.
