During an  artwork, performed with the digital tablet, I have always asked to me which could be the limits, where, was not lawful to go. I found that the best solution was to only use a variation on the digital thick brush and nothing else. No use of filters, not, for a colored image digitally.
This allows me to concentrate on the work without using other instrument except that used from the start. The work is long and laborious, but the result for as far as I’m concerned, is cool and genuine.
Many people say that in the artwork there is not the true but nobody can say that i don’t try to find it.
