This is a set of art trials by the author. Whenever a time allowed 2-3 hours are extracted from busy days. Most of this time comes late at night where everything is getting silent.
Practicing any other activity outside the usual routine is charging and boosting battery performance. I advise doing activities out of usual day-to-day work.
Most of the time I like using electronic pads such as new tablets or pen pads. I have a small Wacom pad and a Samsung Galaxy Note 10.1. The Samsung tablet is very impressive in terms of pen sensitivity to pressure and capturing every detail of pen movement.
I hope you enjoy my humble creative work!
