Tarzan has a twisted stomach muscles. The head looks like a paste. The girl has turned elbow. The animal should have a more flattened skull. Body language is also not clear. I do not feel dynamics. I could write ... But you can see that the picture has cost a lot of time. It is appreciated. You need to hone up on anatomy. Read the book Andrew Loomis for example. Sorry for the criticism. But we are also here to criticize and help each other.
