lol i know what ye mean:)
i can be verry time consuming indeed,but when you use only one kind of paint (exam,oil brushes), you can step away a lit from it,refresh ye head and ome back
but if ye use more then 1 kind of paint? you have to go in 1 go:(,but i think thats not the way to go:(,when you start with a specific paintbrush you should stick with it ,right?
i mean....you almost have to write down what paint you have used before you change, if you wanne go back to that layer to change surten things,thats ofcourse my case!!
there are on Lynda.com good tuts from 1 of the creators of painter,John Derry,and also Jeremy sutton to name 2 of them
there is also a possibility to "steal and save" color palets from famous painters like VanGogh or Monet to us them in your own paintings,
But ,lol, i think you all know that i gues?
best of greetings and thx
