Wow, your mech stuff is really gorgeous! You seem to make the same mistake when doing figures over and over again, that is, you stretch them out of proportions. Especially the whole torso areas seem too long and therefore it makes your figures all alien - look -alike.
As the Bone doctor said > form is form, you understand it, just have to be more confident when applying knowledge to the human body
Keep it up!
the vehicle designs are my favorites...also the self portrait is great...
