To be honest,
I hate the writing.
#1-2 sig render aren't well blended.
All the signature seems messy, need more dept (basic dept: blur the background and reduce the opacity until you go to your render. Progressive blur), flow (I mean we don't know where to look at, there's too much effect)
Overall, it's not that bad for first try though

Every newcomer should get the same comments as I gave you

You will improve!
Don't take it personally
