hello people , So im new to drawpad, and honestly , any of the digital art medias .... but ive been doing art for a lot of years and wanted to expand my experience. Anyway i have photoshop, gimp, drawpad and a few others and thought this one was the easiest to learn. Ive done some research on what i want to do with these programs but still cant figure out how to do it So what i want to do is mesh 3 to 5 different things( eg. a rose a clock and an eye) how do i get rid of the backgrounds of ea original pic leaving only the target. then to i guess layer each target pic to make one final pic. idk if im relaying it right but if someone knows what im saying can u please help
