With these stats (good attack and body balance, good header, bad speed and passing stats, post player star) he looks much more as a classic center forward, a thing that he isn't. Jonas is more an "outside the area" attacker. I seeing (this is the correct word?) him since from his times at Santos, and he was always know as a quality player with wastefull shot.
I remember when Gremio and Santos played for Libertadores da America 2-3 years ago, and I said to my friend: hey, Jonas will play for Santos, and this is a good thing for us, as he always misses his chances of goal
Although he become better at shoting the last years, he is still wastefull. The last game against Boyaca ChicÃ³ is just a good example of this (3 misses in a row).
Now, here's my suggestions:
Balance: 81. People already suggested this. He isn't weak, but certainlly not that strong.
Response: 82-83. He is a very sharp player. He have a great ability to antecipate the defenders, although much people don't see this coz they always remember his miss of goal, as he doing this most of the time.
Top Speed and Acceleration in the low 80s. He isn't a road runner, but he is fast. And much faster than Alex Mineiro. Look at the video he missed the 3 goals, and see the sprint he does before this. Fast player for sure.
Agility: 83. He has pretty good agility. 81 is low for him.
Dribble Accuracy can be upped by 2 points. He has a pretty good dribble too. Also, Dribble Speed is very low. It can be the same of Dribble Accuracy or even 1 point higher.
Don't know why you rated his short passing abilities so low. He makes some good assists. He is a technical player. Short passing can be in the greens, LPA is ok, but LPS is very low. 74-75 probably.
Shot accuracy certainly need to be droped. 76-77 probably. I'd go with 77 probably, coz he become a bit better since last year, and Perea has 76. Although he is still wastefull...
Header is overrated. Don't score from his head that often. Reduce it.
Technique should be higher. 82 or even 83.
Agression can be a bit higher too.
And finally, TW should be higher, as he isn't that selfish. High 70s probably.
For the Stars, Dribbling should be placed over Post Player.
I also think SS can be added as a position, at least optional.
