I've seen some of your stuff before and straight away, the first thing I noticed was the '[c]kayla' (copyright). First, it's a detraction. Second, I would recommend that you don't put that there unless you own everything, which I'm pretty sure you don't. For instance, this:
You would have to own Miley Cyrus if you wanted to put your copyright on it.
Now, with that out of the way, I'll comment on your work. Your vectors, they're interesting but very messy. When you finish one, you should render it to get smooth edges. Your icons, they're okay, there's not much to say on them since icons are simple to do, in my opinion anyway. Your signatures, they're a bit bland and simple in my opinion. You get a stock, a render, duplicate the render a couple of times, place them, add text, and that's pretty much it. That's the style you use mostly. It's just not interesting to me.
I had a look through your old gallery and this is probably your best, or at least one of your best:
Just two things ruin it a bit, the copyright in the corner and the pattern. Having a pattern that covers most of the signature kills depth. I think this is your best because the colors are fitting and you used some effects. The size is also better, but that's just my opinion.
You should also improve on depth, blending and try using fractals and c4ds. Also, never put a render in the middle, and remember the rule of thirds. That's pretty much all I have to say for now.
Some of that probably sounds harsh, but I was just giving my opinion.
