Here's your primary problem: It took me a full minute to find the spartan. You erased too much of it so its hard to discern its shape. And i do have 20/20 vision so dont say its just my vision.
Let me point it out to you. jk lol seriously, I have crap eyesight and I saw it straight away. I suppose it is a bit over contrasted. Just put the original spartan over the top and lower the occupacity a bit. Also, the top boarder isn't completely straight near the right side. You can see the anti-aliasing at work and it should just be a clear straight line.
Looks like ****, no offense. The sniper barrel is cut off making it look quite stupid and the effects make no sense in comparison to him. They are just there and go with him in no way. Also just looks like you used two c4ds and some splatter brushes.
I still don't see the actual spartan o-O i just see part of the sniper i guess. Not the greatest work, make the spartan a bit easier to see and make it a bit less "messy".
Here is the screenshot he used, so he didn't create all the problems y'all are complaining about. I found the spartan immediately, also. The sig doesn't really flow from left to right like at appears intended, though.
Its over contrasted and the splatters, colors, and whole sig together don't work well, the spartans white and then you put in a whole bunch of loud colors next to him. Hardly any flow also... Tone down the sharpness, and the colors some and it would make it better, not good but better than it is now...
Well theres the issue. You need a complete render/stock. It looks like there are just a bunch of low opacity bright splatters besides that though. And guys, its called CnC. CONSTRUCTIVE Criticism. Dont just trash talk the guy.
Eh I really like the signature because of the use of a lot of colors, I think that some parts are more sharpened then other parts which actually makes it look pretty cool. It depends on how you look at it actually. Also the border is like really thick. If you can make it smaller lol 7.1/10
