Piotr Jabłoński, who also goes by the handle “nicponim”, is a Polish concept artist from Bialystok. His clients include Applibot, Inc., Cloud Share Inc., Evermotionvfx, Platige Image and VFX workshops.
Jabłoński works digitally in Photoshop, but achieves nicely painterly look of natural media in his application of color.
His subjects are often dark and moody, and his restrained palette follows suit. He utilizes atmosphere and texture to give his compositions a simultaneous feeling of dream-like fantasy and visceral reality.
There is an interview with Jabłoński on Evermotion.org that includes a step through of his digital painting process.
For a more thorough process tutorial, there is an extended video of his process on the painting shown above, bottom, available through Gumroad.
