Tuomas Korpi is a Finnish illustrator and matt painter who, like many in his field, paints digitally in Photoshop.
His site has little or no biographical information, but has a number of his paintings arranged into genres. I found the work most interesting in the Illustrations section, which includes a variety of subjects including digital still life, and the Sketches section, which includes both briefly noted and more complete digital paintings, as well as some pieces in traditional medial like pastel and gouache.
Despite the lack of other information, he includes the titles of the works and notes the medium, and you can find more detailed comments for individual works on his space at CGSociety, where you will also find some of his pieces reproduced in higher resolution.
Korpi has an effective approach to controlled color and atmospheric perspective that gives his work, even those pieces that are more quickly suggested, a feeling of place and mood.
