I have only one issue with it...
Everything looks great, very well made for photoshop. The contrasting and monotone gives the artwork a more lifelike feel while still hanging onto painting like qualities. My only big complaint would be the head. The mouth line seems too thick and over all the less detailed/shaded head brings a cartoon feel to an overall realistic picture. Other than that, great job! Hope to see more in the future!
