Exhausted From Worry

I draw wildlife to highlight the plight of endangered wildlife and this drawing is exactly the kind of emotion I look for in a subject. This drawing can be interpreted as just another lazy day, but I want viewers to see it how I want it to be interpreted in that this tiger can be exhausted from worrying about survival and how exhausting it is just to that from the myriad of scenarios wildlife is deteriorating. I wanted to capture the lighting and realism in his eyes so that people can feel the docile emotion he is conveying.
