When in Rome, Do as the Romans Do. You're drawing a fat character, so how come you're trying to draw muscles? The artist you're using as inspiration/ref doesn't care about arm muscles here, nor should you here. Take on their mindset and adopt a 2d-shape focused mentality.
As a beginner, and at any skill level, you need to take on challenges that are appropriate for your skill level (challenges that you are capable of succeeding at with effort). Use real photo references where you can actually see the muscles. Right now, what you're trying to do isn't any different from trying to invent muscles from imagination. And when you do that and you lack the knowledge to do it, you're relying on some random person to come along and redline your anatomy mistakes.
You should aim to be self-sufficient by using references that actually contains the visual information you need. You copy the reference once, you put the reference away and then you draw it from memory, or at least something very close to it. The reference then becomes your answer key, your personal anatomy expert that will show you everything you drew wrong.
