Hi, I guess I will start this off in this way:
I recently went on a two week trip to Eastern Europe with my youth orchestra with the goal that I would fill up three sketchbooks. That's a lot of sketchbooks and I ended up barely filling up one.
Although I think I got some pretty good sketches in there I feel like I'm a bit too proud of myself and I need some serious critique to bring me down a few notches. Anyone who can do that would be a big help.

Also some direction or exercises that I could do for the future would be really helpful as well.

Or if that's not how things work in this forum, and I am incorrect in my assumptions, that's adequate as well.
