(Eldar are the tech-y elves of the future from Warhammer 40k, btw)
So two very distinctly different sets of linework, and unfortunately, no .psd for the fairy soli. With semi-transparency in the wings... this one's gonna be a B!7@#...
With lots of work, they actually came out as a rather lovely pair, albeit a little more similar than I would've wanted, but very little could be done with the elf parent's body paint being so light, and without the .psd I couldn't increase the contrast without raping your eyes with uber-dark shadows. Without a body paint, we're stuck with only the jewelry and wing edits to use.
Funny enough, the purple babby DOES in fact haev the elfy parent's base body paint. I only pulled the cracks layer and a couple sparkle layers on hard light, but they buried it even at a low opacity. I cropped out the gems and moved them around as jewelry enhancements, and the wings were entirely going through and hue-shifting each layer. I did quite a bit of painting on the jewelry with some blending modes to try to make the jewelry emulate the textured metal look of the wings. I feel I had moderate success with this.
The second babby came very easily, and I think it came out lovely. The wings were a bit tricky, if you look closely, you can see that the fins behind the wings are actually the fairy parents, as I had to crop them directly, but matching the body color hides it well. I cropped out the efly jewelry and lightened and colorized it to give it a nice glowy cyan coloring to emulate the other cyan accents. The wing sparkles and snowflakes from the mech parent lined up quite by accident, and look great where they are.
