it's a pretty nice tag overall but there are a few things bothering me here man
first let's git off with the text...dont like it very much...might be the font...might be that it doesnt stand out as much as it should in the tag but newer mind that for now
what you could do to improve this is to work on the light source a bit more as well as depth cause the depth in this one looks kinda off somehow...cant really say what exactly
also maybe a bit less darkening those edges
also the tag needs a bit more color or @ least some adjustments to make the focal better
also u could add some effects to the render or something
maybe something like this
You must be registered for see links
the green would go really nice with the tag just use a green brush on some areas and smudge it maybe like i did there
should be easy 4 you to smudge since you have a tablet if i remember
now that there is some green there a green text along with the red one would be nice right?
