Abyssal demon

Digital illustration of a demon to practice, made with Photoshop from a pencil sketch of a concept which is not mine (I can not give credits to the artist since it is not specified anywhere, if anyone knows whose concept let me know in the comments).
I digitized the sketch in Photoshop so that I can apply a base color to add shadows and some details to the beast, ending in the creation of a background with a dark and demonic touch.
Approximately 4 hours of work.
