This was also for my portfolio. It’s an old oil painting which I retouched with Photoshop as the colors looked horrible in the photo that I took of it.
I started painting a pair for this last year; a female angel with a mirroring pose and a red color palette but sadly it is still at the sketching stage.
Oh and I guess I should mention that I got the inspiration from Supernatural for this - I was on spn phase that time. I didn’t however deliberately try to paint Castiel as I had no refs, but the angel does have his dark hair and blue eyes.
