You need to sort out your gig fast!
Firstly, Change it from 3 packages to 1 package for a start. Put a proper description of what your gig is and what your client will get. Remove words like “I’m not advanced”, “I’m new” etc. Work on your strengths instead.
You should also find a way to take better pictures of your drawings (Maybe use a scanner) and enhance it to look better.
You can say something like " I will hand draw anything you want in my own style". You can also provide storyboard services if you know how to visualize and draw scenes. The drawings don’t have to be excellent. Storyboards are rough and simple.
You can do alot with your basic drawing skills. I also think you should get a drawing tablet and learn to draw digitally. That will boost your chances.
