Yes, this one was done recently - almost a year between both of them
I agree about the rendering. These are ZBrush sketches, done at night after work for practice. Usually, I have between 1 and 4 hours for them, if I cut it from my sleep. But gotta practice, right?
That's why it's always just a rough sketch.
That's also why such feedback as yours is always very welcome, as it can help to locate weaknesses and focus more on them the next time. Thanks, much appreciated!
