Here's a few robot concepts I've been working on in my spare time..
I added some text to one version to enter it in a cover art show my friend organized a few weeks ago. Some healthy influence from Ashley Wood but wonky enough that I can still call my own. And yep, you guessed it, all with no backgrounds because I'm quite lazy these days..
The bottom ones are basically recycled / mirrored images of the 1st one. Duplicated, flipped and multiplied in PS to create some interesting shapes then painted over top of..
