Hey Sarah,Great stuff. You have a great eye for character idea. You need to get some line weight in there to maximize the weight and light on the character, it might even help in the train stuff, since they are so stylized.Off to a great start. Good luck.
You are quite right. Looking back and comparing it definitely is loosing a lot of life and feeling (not to mention aesthetic appeal) with out it. I will make more effort to push out of my tidy comfort zones.Thanks Chris!
