You can actually use EDIT MODE, subdividing and then in wireframe mode, use B for box select, and select the sides or faces you want to move instead of that plugin.
The GFX is quite basic, a simple import the character, move somebody parts without using subdivides to get better poses and render and some effects in some photo editor.
Here are some tips:
Firstly, use edit mode (TAB) and subdivide to get better poses as this can greatly make your GFX look better.
In post-editing, take time in the special effects and make it looks interesting and want to click on it or make people look at it.
I think the lighting, instead of a balanced on the whole body, make it shine more on the face or what you are trying to show.
When doing head renders, try showing the neck behind the border, but the top of the hair/ahts above it, so you will have to split the image. This will also improve the GFXs (for head shots and upper body)
FIRST OF ALL, This is obviously not 2 years of designing work, lets just put it there. Two, Lying about the time you have spent on work can get you into trouble, because people will ask “too” much from you.
