Well, to begin with, character design is really hard. It requires a lot of knowledge of anatomy, gesture, costume design, etc. etc. So, the first thing a character designer does is thumbnail sketches to work out their ideas. I did a couple to show you how they should look. I suggest you start there, and then do some more finished drawings based on your thumbnails. I hope this helps :)

I dont know anything about designing a character, but if you want to make a 4 armed humanoid torso i wouldnt spent too much time with anatomy. In reality it would have all the same parts that your arms have, so it would have another shouldergirdle, back muscles, penctoralis whatever. So I would either make the arms not "normal" or just make it look cool without too much tought in to anatomy. you could look for inspiration in animals/insects with multiple limbs. Also check characters like Goro from mortal kombat.

Hey, if you are trying to design characters with multiple sets of arms I suggest you have a peek at some Hindu deities. I think it will look aesthetically more pleasing if the lower set of arms connect higher up the torso closer to the upper set of arms, as if the shoulders are joint together and more in horizontal allignment. Other than that I can see some anatomical errors: the legs are too small, the head is too big and circle shaped and the torso doesn't taper enough towards the bottom. Other than that your off to a great start. Good luck. I didn't draw the attached images btw, it's just as example. Google image search for Hindu deities like Shiva etc..

Hey Aiden, I agree with @Jesper Axelsson critique 100%. This is a cool drawing, and welcome, look forward to seeing more drawings. Including what you have already been told, I wanted to talk about the pose. What you have is nice, but to add more gesture and drama, you could do a few things different. I did a quick sketch to show you what I mean, I hope it helps :)

Hi @Aidan McCulloch, cool drawing! I like how clear the story feels! It's great that you're posting. I think a lot of people feel nervous about making their first post, so you're not alone :) Getting feedback from others is really important. Keep it up💪 - I would highly recommend taking the Drawing Basics course. It will give you a strong foundation that will strenghten all your work, whether that's portraits, comics, landscapes or something else. And Stan seems to have put a lot of effort into making the course fun and motivating. Plus, it's still in the making, so if you keep up with the assignments you have the chance of getting feedback from Stan himself. - In your next drawing, try to look for rhythm between the lines. A curve going one way is followed by a curve going the other way, creating a back 'n' forth like rhythm, that leads the viewer through the drawing. Glenn Vilppu explains it in the beginning of this Drawing Demo by Glenn Vilppu. You might also appreciate checking out @Mike Mattesi's stuff. Looking forward to see more of your work :) PS. Try to hold your camera parallel to the artwork when taking the photo, to avoid distortions.

looks cool as hell, keep it up!
