Here's my first ever render, don't worry about the black mark's on there, I added it so it could look old like a old film.
Its a nice first attempt but you are still leaving a lot of the BG on the render and cutting pieces of the render out. When you try again use the pen tool and zoom in quite close so you do not cut chunks out of the render.
Thanx for the tip, by the way this render took me 40 min's to do and I was about to destroy my computer. I was bored but there it is
Ok a BIG tip dont use magic wand or magic ruber never just pentool or polygonal lasoo because sorry that preety bad im jus tryin to help man sorry
