1.) I learned that for a more realistic artistic space you have to add more detail. For plants you cant just make a blob and color it in, you have to draw each individual item, much like the clouds. I also got a better understanding on size and proportions.
2.) The most helpful exercise to me was the shading practice. I used shading a lot in here, with the clothing, to the plants, and especially the giant robot. I had to think hard of where the shadows and dark places would be, and the practice helped a lot on that.
3.) I like the work for my final project a lot. Not only is it semi realistic with the shading and details, but I also got to add in a fantasy element which made it really fun. It turned out to be successful in my eyes because it's both realistic and interesting at the same time.
