Nah, it's all good - I was just starting up photoshop to work on it some more when I saw your comments. The screenshot is full resolution.
He's not one of my own characters, but I do have a thing for gingers.
As for brushes, hard round airbrush all the way, no layer adjustments like overlay/ multiply unless I'm working with lineart. I do toggle the flow and opacity throughout. I don't really use any other brushes; I imagine that once I have all my basics down and don't have to spend a ton of time making minor adjustments that I'll start making my own custom brushes, but for now I'm happy to carve out a painting with just the hard round.
