You're actually looking decent.
I don't think slim look would fit you best.
You should have some meat on.
By the way, there's no need of going to gym 5 times a week.
It's unnesecessary, especially for people that are not advanced (basically have lots of muscle).
I'm doing great by doing full body workouts 3 times per week.
Your body needs rest and 5x per week is not needed.
Except if you're using steroids, lol.
I've done a 150kg deadlift few weeks ago, and strength is going up rapidly.
I'm going to switch to 4 times per week (upper-lower-upper-lower).
5x per week is ideal I would say. With 2 rest days. Just like a 9 to 5 job would be. It's probably perfect since you want some momentum going. Only 3 per week it may be easy to become very lazy.
Classical "bro" split isn't good (if you're thinking about that).
Your muscles need around 2 days to rest.
So, if you train chest and biceps on Monday, you'll have a 7 day gap between doing that muscle.
But, if you train full-body every 2 days, you'll hit that muscle more often, and make better results.
I have a question for you?
If someone says, if you lift 150kg in bench, would you do it once a week or every day?
Believe me, you'll get stronger by doing every muscle 3 times a week, and not once a week.
There is no standard for how long the body needs to rest. If you are talented in meditation and relax you only need 2 hours of sleep per day. So it all depends on the person. Same as there is no universal diet. If you know your body then you will know what it can do and not do. All comes down to how skilled a person is at paying attention to their own body and how it works.
