/ic/ - Artwork/Critique

Ok
I started drawing 5 monts ago
Now i feeling more "comfortable" with hands
Need practice with faces in perspective and feet anatomy...and other things
In the image im trying to draw witout erasing
Is that a good exercice?
I usually sketch and construct first
Its ok to practice drawing witout skecth sometimes?
Do you have any advice for inking drawings, any book?
Should i start drawing bodies in diferent perspectives? How do i put them in a scenario?
Drawing one image/thing again and again its a good execercise?
How to stop rushing?
How to obeserve details/errors?
Uh...sorry if i explain miself like an retarded but i don't speak/write in english often.
