While I do like this, there's some issues with it. Either it's his head is too big or his body is too small. Also, he has a very small waist for a guy. But I do like the straightness this has. Would have liked to see it colored.

Yeah, I agree with you. After I've finished drawing I got the same sensation about the size of his head...
Thanks for the tips, man! I'll try to get better next time ;)

As mentioned above the proportions are a bit off but the drawing itself is really good! Well done and I love what you did with the MK X text.

Thanks!

This is awesome!! I love the detail and pose you gave him. The head seems to be a bit large, but other than that everything else seems to be in proportion. Will you do a colored version of this? I gave you a 5/5!

Thank you very much! At this moment I won't do a coloured version to it, but soon I will post another drawing...

Still an awesome fan art! He purposely grew a bigger head so he could eat a bigger heart :)

KK has started to grow on me.
