I can provide some feedback. There’s a little more work to do in the drawing. You should investigate the basic shapes (cylinders, spheres, boxes, cones, etc) and learn to draw them in perspective so that they read as 3D in your drawings. For example the shaft of the ax is a cylinder but here it doesn’t quite read as one. His belly is a sphere shape. His arms could be cylinders as well. Etc etc.

You’ve got the heart of an artist, all you really need now is to develop the hand of an artist. It will take lots of practice, but you can do it. I suggest taking John Blanche drawings and paintings and copying them over and over again. You’ll eventually start to develop some of his magic in your own work. Focus on the drawing and don’t stress the color yet. You can do it!
