Yeah, at your current level of skill. You don't really have to sign your name on it, bud. It looks like you focused more intently on making that look cool than you did with the sketch.

When stuff starts looking better, then start putting your name on it. Right now, your drawing has little to nothing positive going for it other than the attempt itself.

Make time to study a bit of anatomy, and how the skeletal system sits and rests underneath the muscle system and how those two tie in together. No one or nothing alive in history has a physical body which looks like the illustration.

Understanding those things a bit more will give your work at least the illusion of occupying space within the frame of your paper, and make it seem like there are 3 dimensions to what you're drawing instead of the 2-d appearance this has. It will also help your drawings seem like they have a weight and depth to them as well.

I don't mean to be harsh, but an honest assessment given to you is more helpful than telling you affirmations or that it's good. It isn't, but that will change in time.

Just study and practice more. Hell, can you find a copy of Burne Hogarths Anatomy illustration books? I may have a pdf copy for you.

I'd give that a few days of reading and study. Maybe some little comic drawing tutorials on yt, and then return to the same drawing with what you've learned. see how it and you improves.
