I'm still working on basic techniques (after all what good is mastering thinning when you can't even yet draw a straight line) so this was an attempt to use the digital camera to notice the mistakes that I could not see even with the magnifying glass.
Rating: 3 Brush control will come with practice, so keep at it. Try to clean up the flash (like on the tip of the axe, the girl's feet) before you prime too. I see from your gallery you are still pretty new (at least to CMON) - you will improve and gain new skills as you go.
