Yup
Yeah, I agree with Rananas. Tne linework and shading is great, and I was looking forward to what you're going to produce. I really like the mottled brown colours you've used as well. Now I think of it, the bobots in the back remind me of Goya.
However, it's pretty difficult to distinguish the body of the robot and the bird from the surroundings, simply because there's not enough contrast. Nae's solution is about right.
Also it's very difficult for robots to connvey emotion, since their features don't move. However, you've done a great job with the pose on this one!
