Well, there is some correlation between strength and size. I am biased however, as I always train for more strength/power than anything. Aesthetics is probably more balance and diet. (one can look big and well built and still be quite light, if one has cuts and separations in the muscles.)
Personally, I feel the compound exercises and focus on the large structures of the body, will still be a best bet for just all over function and a good balanced look. (The legs hips, back chest and shoulders trained with compounds)
3-4 sets of 8-10 reps, 2x-3x per week, while slowly trying to add a little weight over time builds muscle and can still be quite safe.
I am not sold on the machine training, as I prefer almost exclusively free weights as there is no restrictions and standing doing most of my work to load the spine and keep it healthy, but if you only have access to machines, then you can make the best of it.
You list some of your exercises, but no real program, routine or diet!?
How much frequency? (times per week you hit the exercises)
Specific goals? (Having a goal so you can target and focus on a certain thing(s)
