you should work on:
fonts
size
effects
flow
gradient maps
colors (don't change too much colors in one sign)

Thx for the suggestions.

i rly like them especially the 2nd
overall i would say 8/10!

i didnt like it.
Sorry 2/10

At least you should add some suggestions.And tell me what you dont really like of them.AND show me something what you think its good and you like.

They're not simple, they're messy...

There isn't any flow or depth in it, no coordination, and no real consideration in the work.
Be proud of your work, spend more than 10 or 15 minutes on it, look att some tuts or some other sigs to see what really good sigs look like, if you feel like it, you can look at some of my sigs for a start on some sigs that could start you up

They look awesome. 9/10. I like how you did the graphics in a kinda rugged look. I also like the color choices for all of them.

Pretty good ones lilmali but 1 thing...Cant find any flow,depth or cordination tut.And maybe theyre messy but thats my kind of life lol.
BTW,nice sigs youve got there.But still I dont really like the colors...theyre too dark.I like colourful and vivid colors.Im not saying that they look bad,theyre awesome but vivid colors are my fav.

they are very basic, just downloaded some brushes and renders
maybe some effects will be cool
and c4d

Pretty cool what some brushes and a render can do right?
