Hey you... Painter painter run run...

Today, I'm working hard with Painter, which is so great but damn hard to master... It's not a battle won, but I get it slowly and if there are people who mastering in Painter stuff or just a little bit on Painter, I would appreciate their giving me some advice. For personals observations, I wiil say :

1 Be very patient ...
2 Dont be as violent as on Toshop, because your PC will dies before, even if it is a Super Powered PC.
3 Place the masses better than on Toshop, and THEN get somes detail.
4 It's more like real painting... that's the point will say me some people... yes but I use to deal with Toshop's opacity and that all.
