These are really strong base images already, which helps! 1 would be my personal choice because of the more dynamic pose, but either would work... Here's just some random rambles about how I'd do it
>Set her blend mode to Pin Light and then tweak the Levels until it looks good instead of Lighten so you can maintain the shadows in her latex (when considering how much to lighten the bottom left side of the slider, soft light screentones will re-darken these)
>Even if you use default theme, it's probably a good idea to do that on a Dark Theme background anyway if they wear a lot of black (after you have her layer masked off you can transfer that mask to a solid Dark Theme layer so you can put stuff underneath her/start building the rest on blue without it conflicting with her blend mode)
>With robo characters, screentones like I mentioned earlier and scanlines are your friend
>Keywords for stealing cool techy shit from google for the background: scifi cyberpunk aesthetic tumblr UI assets UX futuristic techy future overlay
>If you don't feel like redrawing horns, hand, hair, elbow, etc, you can put a slightly too small rectangular frame on top of her that makes the cutoff points look intentional then erasing it at points so it looks like her limbs are popping out (pic 1 related, doing so saved me the headache of redrawing his cape)
>If you do that, highly recommend sprucing up the frame to make it look like a box or magazine ad or something, also if you want a background color underneath her like white or her gold color layer it beneath both her and the "blend protection" solid layer from earlier
>You might also consider itty bitty flavor text code of lines of code like I have on /c/biometric, I just had ChatGPT cook up some "thematic code for a graphic so it doesn't need to make sense" for me
