Hi there,
Firstly let me say this sounds like an ambitious project, and I can really get behind that.
So my understanding is, that you are looking for a cover, 12 internal illustrations, and I assume a back cover too? So 14 illustrations in total.
I have recently completed an album cover for an Ohio based hip hop artist, where I illustrated him sitting on the front steps of his childhood home, writing lyrics. I feel that it's a good indication of of what I can do for you, though the colours are a lot more subdued compared to the cover for Human Condition. This cover can be seen in my Freelancer portfolio, or alternatively feel free to message me and I can then send it directly to you.
There is a lot to discuss with this project really, and if you decided to go with me on this I'd certainly really like to be able to listen to your music while I'll illustrating these if possible at all. I find that listening to the artist's music always helps me get the right feel to the artwork.
If you have any questions, or just want to talk further about the project, hit me up as I'd love to discuss it all in more detail.
I wish you all the best!
Regards,
Joshua
