Hey on your orbs you notice how on the outside edges they start going flat , I noticed myself when you use select - modify - expand/contract of the selection that tends to happen, but if you use ctrl+t for free transform [ & hold down the alt button to control all sides ] instead to modify the orb shapes that way instead yourself , you wont get that kinda squared look. You might know that already , just thought I'd throw it in there .. it pissed me off when I noticed that squared stuff happening to my own pics lol..
keep up the good work dude.
