4th 6.5/10 needs more flow
5th 7.5/10 pretty good
You're at that stage where you spit out some c4ds and effects onto your background and render.
Work on making the focal of your sig more visible. One thing I noticed is that these 5 don't have much flow to them. Fix that to.
Besides that, just keep working on sigs and you'll get the hang of things.
