Is my workout plan okay?

[iiXAtomXii]

Past year (January 2017 til about 4 or 5 weeks ago) I've been on & off "working out" and being very active. The only stuff I would do with weights though was just basic Dumbbell Curls & Tricep workouts (dips & extensions). I gathered up quite a few exercises two weeks ago and have been doing it since then Monday - Friday.

Here I want to post my current plan & exercises and I want to get feedback, tips, opinions, etc.

Monday, Wednesday & Friday: Shoulders, Chest, Back, Forearms, Biceps & Triceps
