Here's the whole feedback I got:
"I really liked your initial blockout. but your small details seem inconsistent, and not matching the art style set in the concept art.
I would suggest meticulously following the concept art as a useful strategy in the future.
also, be consistent throughout your model. you did small details on the back of the legs, and it seems like you stopped there, and said it was done.
also, consider the role and story of what you're making. I think a lot of the details you added don't looked rugged or armored enough to make sense.
if it's mean to be a game-rez model, be sparing on edges and corners.
if it's not, I SHOULD NEVER SEE A FLAT EDGE OR A HARD CORNER.
add details, and add roundness to every corner. make your circles smooth.
if you're looking to find work, you have a long way to go still, so don't expect something soon, but stick with it, and keep trying new things.
