Do as I say, not as I do

Here are the first 5 random art tips off the top of my head that won't really help you draw, but may help you draw better (YMMV):

1) Don't pet your lines, lay them down with confidence and if you get it wrong, erase with confidence. Unless you're using ink; then you're fucked. In that case, I like to deal with it by changing the lighting scheme and hiding my mistakes in dark, dark shadow.

2) Static poses aren't interesting, make the pose more interesting or change up the camera angle.

3) If you copy straight off a photograph, people will know. Camera lenses foreshadow more dramatically than human eyes; know to correct for it.

4) When using paints, mixing transparent pigments will give vibrant colours and mixing opaque pigments will give you mud. This is true irrespective of the medium (e.g. cadmium yellow is opaque whether it's watercolour or oil).

5) Don't waste your time drawing anime lolis, you'll never get anywhere doing that. <_<
