Preface: I might not be the greatest person to critique something, given that i am just getting back in to drawing and just barely touching the surface of digital art, but i'll let you know what i think. I hope my review is helpful and doesn't offend you in any way.
It feels like there's a lot going on in this piece. My eyes don't know exactly where to go. After looking, i know that Anubis is the focal point, but i wasn't immediately directed to him.
From top to bottom, this piece is overall quite good. Your brush strokes are solid, and the concept of a sort of "Alien Overlord Anubis" is awesome. The idea that pyramids are spaceships is really cool too. That's where "I" start to have other ideas on what you could have done just a little differently. I say "I" because its just my opinion, and should be taken win a grain of salt.
I feel like the two stationary pyramids are fine, light and shadows worked well, but i think you could have used a lighter shadow, and darker details to make them pop a little more on the shadowed side. Just because the objects aren't the main focus, doesn't mean you should treat them and different than your main subject. The same can be said for the spaceships, at least i think they're spaceships, in the background. They feel almost rushed, and added in because you felt like there needed to be something in the background. Not to say they shouldn't be there, but if they had a little more detail or did something to help identify them as what they are.
Moving forward, the road. I love it. It looks natural and well thought out. it seems like each stone had purpose and it belongs exactly where it is. I think the tumbleweeds are a little much. They don't feel like they fit into the desert theme, and i feel like you might of thought the road felt empty or something.
Finally, Anubis. The figure looks good, proportions are good. The shading looks really good, especially since you've got 2 light sources, the moon and his staff. The subtle purples in the highlights on his front are a great touch. The only thing im curious about is his shroud on his neck. I feel like it could have been made just a little taller, because it feels like it gets lost in the structure of his head. It also feels like the headdress is on a different angle than his body. His face mask it also a little weird. It seems almost "painted" on. It follows the same color scheme as his headdress, but something just seems off. His eyes seem to have the same effect for me. It feels like there isn't much depth to them.
In conclusion, this piece is really good. I know i might have pointed out a few things and it might seem harsh, but i really do like this work. All my qualms are minor, and can be addressed quite easily. Keep up the awesome work, and i cant wait to see more from you!
