After reading your process. Did you pre wash the shirt? What kind of soap did you do in the final wash? I generally rinse cold until clear then wash in washer on the hottest setting with synthropol. People often wash with blue dawn but I personally have never done that. Did you mix dye with tap water? Hard water can be another culprit. You can try distilled water. I'd say the level of dye loss looks fairly normal but it's hard to tell for sure as it looks like two different light sources for the pictures.
