in 3 you need to bring the render out, its not that the tags flat its just that its hard to see him, so try to get some more colors going in the tag with efx behind him, then if you want map it so it brings the colors closer together. its just hard to focus on the focal imo.
1/2 is good, but it looks like a WIP,, it needs some bright efx, maybe star stock/c4d, what you did was use dark efx, but it looks empty bc they're dark, use bright efx aswell and it'll make your tags look more complete.
