Maintenance goals

I’ve been doing a workout at the gym of barbell back squats , flat bench press, and chin ups along with lat raises up until this point.

Recently with college coming up and the fact I won’t be playing I have the time or really the motivation to go to the gym so I plan to just do a fast hassle free home workout. The goal is to do 100 pushups, 200 body weight squats with a calf raise. And use a pull up bar to do around 50 chin ups. Two maybe three times a week. In the meantime I’ll just take them all to failure or do sets since the squats are the only thing I see myself completing to my set rep range. Once that gets too easy I may incorporate a weight vest.

My question is does my new workout still likely maintain at-least relatively to my old workout in targeted muscles. And the bigger question is does it create any major muscle imbalances I need to worry about as I spend a lot of time at my desk studying or drawing. And I’d like for my posture to be strong.
