So, the biggest issue I see with your designs is the lack of dimension and structure. Just because something is cartooned, doesn't mean it doesn't adhere to the same rules of structure (unless it's a very stylized design). I did some sketches to show you what I'm talking about, I hope it helps :)

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 :)

Maybe it's not the drawing, but the pressure of homework, or drawing what somebody else tells you to draw rather that drawing for the joy of it. Or maybe it's not a good career choice for you but rather a leisure time thing. Some of my very best classes were taught by professors who made incredible drawings to illustrate their lessons. Maybe they didn't want the pressure of trying to earn a living with art. I became a nurse, so there has never been pressure to perform with my art. (which I hated). Good luck with this - sometimes you feel worse about stuff when you're very tired.

I think those are very good. The only thing is that they are a little too detailled for gesture drawings, there are too much muscular shapes. Try to find the flow of the limbs. Some great exercises to transition into the anatomy course are the robo bean and mannequinization. Good luck

Hey Athul, These are really nice drawings, the proportions are good and they feel solid. That said, I think these are not pure gesture drawings because you have added anatomy to the contour. That's not to say that they do not have gesture because they do, but gesture drawings start with a line, either an "s" or a "c" shape from top to bottom of the pose. Then that gesture carries into the limbs and so forth. What you have though is nice solid figures. So, I think you should step up to adding some light and shadow to them. Not full on rendering, just a core shadow and some tone to fill in the shadow. I think this will really elevate your drawings and will be a good transition to full rendering when your ready. I did a couple of examples over your drawings. Now, I don't have the reference, so I just made up the shadows based on experience, but I think you will get the point. I think your drawings will look really good like this and hope you give it a try. I hope this was helpful :)

I wish I could paint like that 😍. Awesome work (❁´◡`❁)
