Maybe you are right... but I don't like coloured pencils.. and I don't know much about art stuff... I really love monochrome drawings made from graphit... However, I use watercolours for cartoons sometimes...
wow!! this looks great! i love the nose ^^ beautiful job esspecially with the form! the colors in this look great as well, esspecially the dark part of the suit. i do agree with bluemattersoda, more colors and contrast in the skin would really make this an amazing piece.
pay attention to angles going down as well! they look great until her right foot, i get a little thrown off as it looks like the ground is sloped a bit.
very well done! i can see the attention to detail, so congrats! but if i had to critique it i would say that the skin seems a bit dead, so maybe use a more lively colour for her skin. but nonetheless, excellent work!
