Excellent work here, you pull off this lineless, detailed style very well! I really like the subtle lighting and colours you have used, as well; they all come together brilliantly to convey a menacing atmosphere. I could definitely see this being a piece of concept art for a real animated film or series!
If I may ask, how long did it take you to do?
Congratulations on the Daily Deviation as well! I don't believe I've seen a cartoon/anthro piece as one before, which makes it all the more remarkable!
