Park Sketch (Penciling LIght and Shadows)

Ok during this phase, I have gone over red and blue line work with a 0.7 mechanical pencil and as you can see the concept is starting to take form. I also used blue, red, green, and purple colored pencils to plan out my shedding, I wanted this piece to look like it was backlit sunset, I don't know if this is considered a color study or a sketch study, but I think that's what I did. If anyone sees this, I hope that they like what they see, let me know what you think in the comments section I'd love to hear some feedback on my artwork
