I don't like the orange thing in the front. Imo it would look a lot better without it, period. And if you want to keep it, the sides are like blurry but pixely...fix that up.
idk seems kinda plain to me, not liking the black effect, and the other c4d or w/e appears slightly pixely and akward on my screen it stands out where the render focal is kinda flat alogn with bg nt mate, just not to my liking
1st version is the best, but I really think you should get rid of the dot on her shoulder. It doesn't really look that good.
