Gothic Brides two

I like how you gave the detailed of clothes(right one) I can sense you try hard to put detailed on it and like I said, I like the way you done it. I'm not much a good critique, So I might not have such a sharp eye or sharp tongue. But all I could say is "Practice is the key" Try to do this everyday and you will soon understand it.
Now for some suggestion, First one I see that your designed was really unique but still need an accurate on "perspective" all you need is something to guide you, And that's where "google/picture" in. All you need is a key word in your mind search google for material learn and memorize as much as you can. Digest it and express it out on drawing. That's how you spice up your picture
The second one is "guideline" I bet you already see it right? Match stick figure was one of them as well. Use everything that reassemble to your character (Triangle,Line,Circle etc.)
Last one, Always appreciate what you did, Do take the "criticize" But don't fell or get too personal with it. Try to use them as "next improve" subject.
Be well, And practice a lot!. Good luck.
