Yes, the horn is most obvious, but I think the bottom jaw is a problem too. It looks not in place, twisted. Imagine how it will close. Both jaws will not meet properly. 

Very good design! Although it's not finished, it's really catches they eye of the viewer. I like the expression, love your line quality. Very clean and exact. You may try to use some line weight for extra effect. It looks you have put a lot of work and imagination to this sketch.

I'm seeing one problem about perspective. It looks if you are applying the perspective rules upside down. Instead of shrinking into the distance, the forms are scaling up. To see it better, try to draw straight lines from two symmetrical points (bottom of the nostrils, base of the top horns, teeth, bottom jaw, horn segments) and extend them. This lines in real life are parallel to each other, but according perspective rules they have to converge to the distance at a point (vanishing point). Now they are moving apart as they go away of us.

It's a lot for correction, but if you try to solve the perspective your sketch will look more 3 dimensional and realistic. I see this artwork have great potential!

I hope this critique is helpful for you.

Thank you very much for your critique!

It's very helpful to hear your opinion. You are right about mountains and pathways. Some more details will be beneficial there. I'm reserving the right to make this change

Thanks again!

Thank you very much for your critique! You are right. It started as a doodle. Main goal was to try to extract any idea from it. I will try to add some light to lava just to see the change. But I lost motivation, energy for this image to make second version. Next time with the next image I shall put more effort to make it better.

Thank you for you critique! I agree with you about the dress. I was too focus about other details and didn't pay attention to it. I will correct it soon.
