This is my harvest, if you have something that seems to be a plagiarism is pure coincidence. It is practically made from scratch.
it's not about plagiarism, but when you borrow bits of other drawings, you need to add credit to the original artist. The credit line would be, the name of the original artist and you name next to it.
We all do it, have many people that borrow each other drawing, but we always credit.
It's nothing wrong, that you use others drawing, so long you remember to add credit.
For example, notice how "Sebu" have credited other artist for borrowing parts of there drawings.
And you should also post you're drawing I either personal drawing or in Alternative universe topic on this forum. Never build design topic is only for ships that was designed in the real world but never build, not fantasy.
BTW. we are not here to eat you!
