Let's start with some things you've said so far Sumenoe
I don't remember exactly but I have been drawing seriously for.... 7-10 years.
One year I managed to draw only one drawing. Thats how long I spent on it and I'm not happy with it
I do work hard. I didn't just start. I have read about human anatomy.
I have gone to many perspective drawing classes. I supposedly know how to draw rooms with different perspectives. But all that knowledge goes away when I try to draw.
considering all these statements and what pictures you've shown make for a bit of an awkward disconnect. fact is it is hard to understand how these two differing things can exist at once. Obitual Crow is on the right track of understanding; as drawing seems to be more a game of understanding over knowledge. but the fact remains if you truly have been at this for 7-10 years as you say then why is THIS
the best you seem to be able to muster, which though a vast improvement over a lot of the other stuff in this thread still doesn't show much of the understanding that should have seeped into your mind over the years.
Most likely because this understanding is not being allowed to seep in, you have essentially fortified an airtight seal against it whether you are aware of it or not. basically what i am saying is that you have likely erected (subconsciously with a good likely hood) a mental block that until it is removed you will never progress past. Of course if this is true it still doesn't help much as the matters of why and how this block came to be are only to your knowledge (i might wager money on the hand thing making at least some small factor assuming you weren't born with it) and it's hard to get you past a block without those.
Of course i am no psychiatrist/psychologist so do take this with the necessary salt.
This might be the problem. When I think about drawing now, in my mind, I can see myself drawing all kinds of stuff and understanding the shapes and stuff. But when I actually draw, all that goes away and all I see is a white screen. If I draw something, all I can see is random lines that look like nothing. Every now and then I manage to do something and it seems like I have read something. Next time I draw, I start almost from zero.
I have no idea about any blocks, except that it seems that my whole mind goes to sleep when I try to draw...... About the hand thing, I did and did not born with it. It is a small part of a bigger problem that I had since I was born and it got worse. It will get even worse. It wasn't that bad when I was young, I didn't really even notice it. All I could tell was that writing exams with pen was a silly goose for me.
