My teacher said the two drawings are extremely schematic and should be improved in quality，but i do not how to improve it. Who would give me some advices？
You need to use a different repository for the pictures, because Snapfish requires an account even to just view the pictures.
Thanks， I get it.
What are you trying to show with the drawings?
The top one is the famous sacred cross of the Wankers League whose young members troll forums trying to find people to do their homework for them. Their club initials WL are on the side. The second one is anybody’s guess.
Sorry for later reply，it is for a research paper. Editor think it is not a good abridged general view.
Gcaptain is a good place for technical exchange. We must value and make full use of this.
