Hey Athul Krishna, Sorry to hear about your frustration, it's the price of being a good artist. Also, don't think that drawing in a stylized way is any easier than drawing realism. They are not seperate things, just different expressions. Your stylized drawing is a good example of that. You didn't use gesture or structure to build your drawing, and it looks flat and stiff. These are the things we learn in realism that carry over to other styles. I did a quick sketch to show you what I mean, I hope it helps :)
