The night is no rest when the day is too short || digital drawing

For much of my life, my OCD didn't cause me many problems. But after I entered adulthood, it became obvious to me that it was a massive problem for others. And a while later - it got to me that it was stopping me from doing what I wanted to do, or rather how I wanted to do it.

Of course, the condition is no limited to work-related subjects only. But my work is my lens, since, it is really difficult for me just 'sit and relax'.

I work in Adobe Illustrator on a day-to-day basis, which can make life easier - centring, or reflecting an image, is just a moment of my time. Nevertheless - matching colours, choosing the 'perfect' swatches or fine-tuning designs down to the smallest detail - it may sound good, but it makes my 'efficiency' virtually non-existent. I spend hours instead of minutes on certain tasks because 'something is getting in the way'. And I spend a long time looking for that element which is disrupting the composition....

In terms of work - often I frustrate others with this. And I also frustrate myself. That's why, from time to time, I try to work on a project with an ABSOLUTE DEADLINE BEFORE DEADLINE. I set myself an alarm with a few 'stoppages' for particular parts of the project, and I have to force myself to meet the deadline not only every second - but also to let go and leave a project which, in my mind, still needs a ton of work.

About the drawing

This is just such a project. I gave myself exactly six hours to finish the drawing. Half an hour on sketching, an hour - to pick the base colours - and the rest - looking for colours and working one the details. It is almost painful for me to show work that I think is unfinished, but it is a form of self-therapy. This is not to say that I don't rely on your honesty and constructive criticism. On the contrary. I would be very grateful for your comments. I still have little experience with 2D-digital drawing, and I very much look forward to your advice.
