hiThis has great perspective. I like how the shark looks like he is coming right out of the picture and going to come right after the viewer.I really like the detail in the mouth and teeth and eyes. Very realistic looking in my opinion. The texture and shading of the body gives the viewer the feeling of smooth skin that is associated with this animal.Excellent work on position also. Frontal views I feel are very difficult because of fore shortening. I think you did a very good job on that part.The background and foreground do have good perspective and they do give an illusion of the vastness of the ocean.The addition of the sea bottom land mass on the left side of the drawing gives the drawing a balanced to the composition., but would have darken the bottom portion of it to give it a little more volume to balance out the weight of the darker tail on the right side.The Jelly fish add interest to the background without detracting from your main focus of the shark.The one thing I would suggest on the back ground is to smooth the lines of your water just a bit more to give more of an illusion of water.Out side of a few minor things. I feel you have done a great job on this aquatic animal.Critique done by Inspiring Creation
