I worked on this my style last 3-4 years. A lot of people in commets asked me to show how i make that oily strokes. Well, glad to introduce you my video tutorial (~23 min on RUSSIAN with ENGLISH SUBTITLES) about my digital oil painting technique - IMPASTO. Сompatible only with Photoshop (ver. 18 and higher) and not for beginners, i guess. It's my first full video tutorial, it was hard. Hope you find it useful.
