Hey there! Thank you for your enthusiasm. To be completely transparent, I did not draw the artworks used in both promotional pieces. I commissioned artists to draw both Beatris & Vika. 

In Beatris' case, the artist also made a background which I reworked into what you see. As for Vika's art piece (1919), I found free to use images online, cut them up in the shape i needed them & recolored/decolored them to give the image a setting. (Each image needs a focal point & so Vika's art piece is the red chip which i mirrored horz. & vert. To make it look like a motif.)

You might want to look into Photoshop's Levels tool for color/light balancing. Its my main tool to create these edits.

Hope this helps! Cheers!
