i used to watch tmnt as a kid and i loved it. seeing them in this style intrigues me. its a brilliant picture, you've captured their characteristics in a few lines, which personally i find very hard to do, and the proportions and body language would tell more than the words if it didnt have speech bubbles. michealangelo looking very bombastic, rapheal looking dominating, leonardo looking over at michealangelo looking fed up with his stupidity and donatello looking very closed in very shy. all in all very well done i applaude you good sir. originality a 4 because alot of people have done it before. impact a 5 because of the range in personality. like ive said your proportions are perfect and your art style is awesome, just ink, and technique a 4 and a half because lots of people use just black and white but to get it right, thats different.
Looking over this picture I can't help but notice that you've taken a basic 'gender-reversal' picture and really worked hard at doing more than removing a Y chromosome. In the past with the male designs it was usually only by color-coding their gear or the dialogue that you really could tell one apart from another. With this one, it's the small touches that really help to divide up the characters. Leonardo has a lean gymnast's build, her eyes ending in lashes that swoop upwards, suggesting more classic 'Asian' features. Her mask's tassels have only small signs of wear and tear indicating the danger of her fighting with blades but having enough skill to avoid serious injury. Donatello's wide expressive eyes end in slight upward eyelashes that are more hook-like, and her mouth is missing a tooth. Her own form is slender and yet doesn't look as agile as Leo's. The way she stands sort-of huddled into herself and cradles her weapon in her hands betrays her insecurity to give voice to her having hobbies that her sisters do not share. Raphael has the heaviest build in sheer muscle. Everything about her body language and design says that she is not afraid to get up close and make things personal. Scars, healed cracks in her shell, the ripped tassels on her mask, even the way her eyes end in a nearly horizontal point of eyelashes as she narrows her eyes as a result of Mikey's antics. Michelangelo's design really adds a new dimension to the character. Carefree and light on the thinking, she stands in a fairly carefree and expressive manner, without doubt or anger or even control. She comes across as a someone who is in it just for the fun. Her eyes are wide and expressive, ending in multiple eyelash points, and the freckles add to her cuteness . One thing I note is that her body is the curviest of her teammates, still athletic but more like a cheerleader. No doubt this bouncy bubbly version of Mikey got this from indulging in her slightly hedonistic love of Pizza.
