Draw or paint something every day. Practice makes perfect. Keep a journal or sketchbook.
Work on multiple paintings at a time. I don’t always do this but it is my preferred way to work; it not only decreases wasted time but is helpful if I’m stuck or frustrated with a particular piece. Often, while I’m working on another work, the ideas for the set-aside piece become crystal clear. – Via Jennybird
Don’t try to fix a mistake with more paint, remove it with turpentine.
Pre-soak your paper in the bathtub and lay flat, even if it is already pre-sized. - Via Annie Owens

Photographing Your Artwork
It’s always best to scan your artwork and keep a high resolution file. If you can’t – then take the highest res photo of it you can, before and after framing and before you put it in a show. The best way is to stand over your art with it laid flat on the floor or ground. Line your camera up so there the edges look straight in the camera frame. Take 5-10 pictures – a few in natural daylight (shade), a few inside by a window and a few with lamps or lighting. Try not to use flash as that will create glare in the finish. You can adjust the contrast and crop the edges of your file to make it look square (if the image looks warped) in PhotoShop or another software program. Always save a high res version.
