so im not sure exactly where i was going with this. I kind of just c4d spammed it and then took out all the ones i didnt like. I made 2 versions. Black BG and White BG. So CnC plz
I'm not sure which one to critique so I'll do both. Well, to start off, you shouldn't randomly put C4Ds on a canvas. Each C4D should have a purpose of where it's located. the particles flouting around could have been used properly then just simply placed on the render. I see you tried to put the particles near wolverine's chest, making it look like there's a dissolve going on, pretty nice, but the same C4D is used at the bottom left of the tag. Work on that!
Now let's talk about your lighting: Firstly, it needs more work as it doesn't fit with the render's lighting conditions. Try playing around a with soft brushes a little, you'll get it. Also, a good way of improving the relationship between the light and the render is by looking at where the darker and lighter portions of the render are affected by light. Your spider-man tag right below you nails the lighting really well. I like the second tag because the depth works really well and the background looks better overall. Kudos for that ;)
