Hi.
If you want to draw better Shipbucket drawings, please
use the shipbucket style guide & standards manual.
While you may be able to draw anything you want, it is better that you start off by “kitbashing” drawings from other users; be warned that you are to credit the original artist, should you “kitbash” a drawing from that original artist. Using parts from other artists also apply; usage of real-life mass-manufactured components either from parts sheets or something do not require a credit to the original artist.
Get along with the community and get some help from more experienced users of this forum if you want to better your drawing skills.
Welcome abroad to the forums.
PS: Please use references if you want to make a certain drawing. They really help you draw something good.
