Some foliage and trees in the background are brush shapes. So I didn't spent a lot of time with these parts. I think these elemnets makes this painting so rich, digital painters with 5-10 years routine are finishes this picture about 1h (max). I have only one year routine as a digital painter (photoshop/artrage/sketchup for structure modelling).
I have a lot of trouble with these (compose, feeling, color) but sometimes I can imagine the right and exciting mood. Yep it's hard, we should practice more and more. Some of my pictures are boring but who cares? It's just practicem, I wont rule the world with these pictures . I recommend you to watch a lot of tutorial video from FZD school's channel on youtube. Very-very useful!!!
