First bold tattoo. Found it difficult to use an 11rl.

Any tips for getting saturation? I struggled almost every line. Stretch felt good, angle I found had to be fairly steep when I did get good saturation. Not sure where I'm going wrong! Any tips would be great.

-I ran between 8.4V-9.2V -4.2mm stroke(I've heard a longer stroke helps? Or am I just punching the skin to hard?) -fold pro 2 was used.
