I’ve been reading through the ’60s “Famous Artist Course” as well as   watching illustrator demos on the
 Visual Literacy  Program. I feel like I’ve  learned a lot lately and have added some  “things to keep in mind” to my  “things to keep in mind while drawing”  list. many of these are “obvious”  and get said over and over again. but  sometimes, it just takes hearing  it ONE more time before it clicks and  really makes a difference. There  are a lot, but here are jusr some of the  new ones that I’ve been trying to  apply…which is easier said than done.
- 
Think in big shapes  first. This one is hard for me. I  need to start developing thumbnails that reflect this idea. Design with  shapes. Gary Kelley is GREAT at shape. Tagged along with this  sorta  goes the idea of strong silhouette. for instant, powerful reads,  the  image will be most effectively designed if i consider my large  groups  of values.
-
Not every image needs a full value range. and not   everything in an image needs dramatic value range. applying a simpler   value structure to my big shapes will better help me design and image   and create better focal  points. Again, another difficult one for me.
-
Detail can kill you. guys like mignola and Al  Hirschfeld and alex toth got this nailed.  describing things in as few  marks as necessary (again, silhouette comes  in here). ? put detail  where you need it to reinforce focal points, but leave  it out where it  doesnt matter.
-Use saturation wisely. im’ a sucker  for  super-saturated images, so this one is tricky for me.
-Make a  confident mark and LEAVE IT ALONE. it’s better  to be slightly wrong, but  made confidently than to have meticulously  slaved over, indecisive  lines that try to be perfect.
-embrace the medium. let digital look  digital. dont try to make digital  look like watercolor. just use  watercolor. dont try to make inks look  like vector art. let them be inks.
-Trust your  instincts and embrace failure. there isn’t  necessarily a “right’ way to do things. you  can’t please everyone.  George Pratt often says something along the lines of: if you aren’t  screwing up, you aren’t doing it right.
-Every part of an illustration matters. think  about  how every piece is impacting the drawing. pay attention to every  part  and resolve it appropriately.
-
You can’t save a poor drawing. you can polish a good  drawing in a billion different ways. but if the  foundation stinks,  style can’t save it.
These sound so easy, and right now it's more of a checklist in my mind, but I'm hoping it becomes more intuition as I practice. John English recommends thumbnails to be 3 values, no line so it's really shape design. I've only played around and it's already so helpful to establish a good read.
Any other ideas?
