@cyangmou Thank you very much for your post. It was very informative.
1. I have changed my background as suggested. I am thinking of a more of a desert setting on a sunny day. So I changed some ofthe colors to try to match that kind of match that setting.
2. I wasn't quite at this step yet on my last post, but your reference really helped me. I tried to focus on shading the bigger parts. I touched up the shadows of the roof, and parts of the wall.
3.I added a cast shadow of the entire building, I know its not the best cast shadow, but I am willing to work on it.
4. I actually started out drawing the lantern with curved edges, but I thought it looked weird because I didn't color it at the time, and I got kind of frustrated with how it was looking. I tried to implement your suggestions.
Thank you for your feed back, your advice was very helpful. It looks like its really coming together now.
