I think some of the problems with the lines on its right arm is that it's really rough and jagged in an inconsistent way.

With the contrast in the greens, maybe try making the middle shade a little bit darker, since it's right now really close to the light green but too far from the dark one.

Here's some edits because I don't think I communicated well in the above paragraphs lol:

I mostly just tried to make the right arm less jagged by making the few instances of jaggedness more consistent in slope. Not sure if it actually helped at all.........
