Draw more Anime

so far ive got my feet wet drawing this and that, but i need to learn how to draw all angles of faces, get the wrinkles right, get the shadows right, adn get some scenary done. i need to get good enuff and not just copying ( i only copy the facial parts and most of the time i draw at school so i don have ne thin to copy from), i need to make a drawing equivilant to the talent in “Paradise Kiss”. which is btw a AMAZING anime. :D
