It's not as bad as people are making it out to be. You're only getting spammy comments because everyone seems to hate you here. Friendly tip: don't talk about your problems or how lonely and depressed you are. Maybe I just got unlucky, but most of the posts I've seen from you center around that. It makes you look like you desperately want attention.
Anyway, here's a little criticism. When drawing people, never draw their backs straight. The bodies you drew look like boxes and that can really ruin a picture. Next, the arms don't look like arms. Go look at other professional drawings and see how arms are drawn, or just look at your own in a mirror. Do they look all straight and boxy? Also, the hands are not drawn correctly. Depending on your style, they can be drawn big or small, but just keep in mind that in real life your hands are almost as big as your face.
I think you're main problem is that you drawing body parts straight. It's a very common mistake. Don't do it, look at how they're really drawn and COPY.
