It kind of looks like the focal is a bit weird. I think the blurring needs to have a better transition. Good colors and blending, lighting is decent, just work on that depth issue.
The depth of field here is literally all over the place. The farther away something is, the more blurred it should be. The C4D's also take away from the realism. Overall the tag is alright but the colors are just not appealing to me at all.
