I like the first 3 10/10 on those and the other give them 8/10, good job on all of them

You seem to use way to many anime renders. Anime is very easy to work with as there are many colours that go with anime. try some real life renders or video game renders that are life like. I see the world at war one but it looks pretty bad. to improve you msut work with different renders anyway to the signature's. 5/10 for all except last one 1/10

ugh dont like at all watch tuts ull be good sum day

Cool nice job man I like all of them 10/10

good job, i just think they're a bit simple and plain.. add some more effects, c4ds..
just be a bit more creative xD.
i think the first one's the best but the bg looks low qaulity..
