I was having a hard time with photoshop i didnt learn how to use it very well. but now i discovered Paint tool SAI... its WAY better. the linework is easier. Highly recommended its a very good and usefull program.
Todos mis programas de dibujar son portatiles, no se si eso le quitará algunos complementos pero hasta ahora me va bien con photoshop, ilustrator, flash y Paint tool sai. si encuentro algun otro buen programa para dibujar via pc lo comento por aqui
