>>1870562Here are some last few issues.
The iris colors within the eye are very poor and lumpy. Take advantage of using the circle tool. Make the circle shape, and get it as close to the shape of the outer iris as much as possible. Then, make a second shapes, starting outside the circle shape, that draws the internal crescent shape, and make sure the outer parts of that shape go above and around the top part of the circle shape. Then, select both shapes, open your Pathfinder box, and select "Minus Front". This should delete properly and give you a crescent shape with minimal and smooth nodes. You can then add/delete nodes and play with handles if you need to get a little bit closer to the original. Do the other iris color on top of it in a similar fashion. You can turn on Smart Guides (Ctrl+U) if you need help latching a node onto another node, or another shape.
The blush has some banding issues. Make sure you have the outer radial gradient color set to the skin color behind it, and spread the coloring a bit more. This should help hide banding. For the right arm, don't create an odd shape where it bends severely. You want there to be a clear termination for the two arm lines (see original). Instead, make them two separate shapes with one going over the other. For the left shoulder, do not have the arm line going over the collar line. The collar is on top of the clothing, so the two should be switched, with the collar line going over the shirt line. Anything else not mentioned is consistency issues, or lumpy lines.
Use RGB for the most part, as most vectors will be used for wallpapers. It allows for greater color ranges than CMYK. Also, if you right click the image and use "Open With" and select Illustrator, it will open the image as RGB by default, with none of the unneeded swatches and graphic styles.
