Hey Sorin, This distance from the table looks absolutely fine to me, and your overall form is starting to look better as well! I think this type of exercise and training is exactly what you need to develop and improve, the more random ball placements mean you have to get better at decision making and those small movement adjustments!
I would say keep going with this and focus on keeping low as you move across the table and your head at the same height which means you have a stable position to play from. But your distance to the table is fine and I can see a lot of the technical areas you have worked on are getting there too!
