Thank you very much! I'm glad yo like it!



Sorry, I have no video tutorials yet, I would like to do a few a some point, but I still haven't found the time for that.



About brushes, I believe sticking to the basics is the best... I'm currently using a round brush to draw, and a square brush with a bit of texture and opacity set to pressure for painting. That's usually enough to do at least 99% of a painting.



Regarding your painting, I'd suggest to check the values, they're too uniform. Elements in the foreground should have more contrast. Also, I understand you're going for the a loose painting style, but even that way I would add some more details to the main mech, that would also help to separate it from the background.



Hope it helps!
