nice one. I like the progress so far on the train. How comfortable are you doing it on the pen? You can get cleaner and precise line with pen or we can adjust it in photoshop after you finish with pencil. I like how you leave some parts just with lay in lines. But make sure they are fading naturally not too sudden. For second one, let's just finish the lines. Overall we might need to push and pull line intensity.For the painting. I would focus more on the house group in the left middle ground in terns of density and values, also reduce the light brightness on the right foreground. I'll do paintover on this one tomorrow with color. good job~!!
