No offense, but I find it hard to believe that you made those.. If you did, they're not too bad actually. One or more things that could be improved is the blending on the first one. It would be better if the gradient maps and photo filters you used would blend well with the effects you added. On the second, the render placement doesn't actually show me where I'm supposed to be looking. I think the focal of it should have been more to the left .
i made the, lol and im not trying to show you where to be looking its pretty obvious. its not blended thats why it stands out. your eyes shouldnt be trying to find it
You definitely need to blend the renders. Not blending the renders is not how you create a focal point. You crate a focal point with correct lighting, brushing, and other eye-catching effects.
The c4d's seem placed random, although better then most tags posted here. It doesn't have a real focal, depth or anything else really. Creating a nice tag is more then swapping some random effects c4d's with a render in it.
If that was sarcasm. I'm just trying to help you, if you don't want me to post in any of your work again just tell me.
Well second looks kinda good, but I don't like all those c4d's at all. I'd give it a go if it was your made c4d, but I prefer adding more simple effects you add instead that you use those stocks.
