This is Marta Dahlig. She is an amazing artist from Poland. She paints awesome pictures of women with storytelling elements to the illustration. You can find tutorials she has created for imaginefx on a regular basis. You can find samples of her work at www.marta-dahlig.com
On a technical note, I used a brush she created which I got from one of her aforementioned tutorials. I took a different approach when creating this image. I started off doing line art work (like I usually do) but after a couple of minutes into the painting, I decided to change the technique and worked on the silhouette. After the silhouette was established, I started defining form with light. I started with a medium dark green tone over a light pink background. I used a 70% opacity on the brush and this helped me get loads of color variation. I used the ALT key for color sampling and continued defining form. I added a NOISE filter at about 80%. I desaturated the image completely.
Hope you like it.
