I used to be quite the sketch artist years back. Some of my work is posted under my older deviantART account under ~vertigoelectric.
I was never any good at drawing people for some reason, therefore I was not good at drawing manga people. I would try again, but I don't really have it in me any more. The past few years I've tried sitting down and drawing something and I just can't do it any more. Not sure what's changed.
I saw a few drawings on your older account. Well if you wanna draw you must try. I sometimes have problems with some drawings. Then better cease draw and the next day draw. On the internet are many courses how draw, but one must try. I wish good luck.
