He watches and makes notes to himself as to what could be approved. The brushes and 'ink' are serviceable but in a situation like this, every little problem becomes highlighted.

[Not too much as to burn the paper but just enough to be able to sense where previous strokes had gone...but perhaps there was a way to minimalize the waste. Perhaps some kind of seal could be applied both to make the energy slower to dispel and make the consumption less. A carved stamp, maybe, for ease of application. He idly traces the idea of a seal on his own leg as he just...wipes the paint off on his sleeve at the same time. Look, he's been wearing some magically stain proof robes, that tends to lead to bad habits.]

More practise and tries will be needed.
