Which color

I like the blue one better because the other one looks too Halloween.

 

You should make it red and brown.

 

Idk, it doesn't matter to me.

 

Go with neither and make the background more interesting. This is way too monotonous.

 

Well, I don't really like either that much, but orange is better.

 

I like them both, but for the blue one, remove the half border or make a full one, it looks out of place.
Maybe add a full one for the orange one too.

 

The sig itself...is meh. I'd go with blue. Lose the text though, it does NOT fit the sig.

I think the blue looks better, but maybe you should make the edges of the post kind of fade out instead of just putting a border around it.
