I have written art and tips because art can be very interesting. It can sometimes produce results even without having tips from other people. It is not the same that you take tips from a senior artist or a fine art broker, then only you will be able to make something out of the ordinary, it can be anything. It can be done without tips also, but better it is to use the tips, these can involve a lot of things. Here are a few drawing tips, that will help any person improve their drawing skills. Read these and I am sure that you will get something out of them. These will improve your art. 
As a right hander, the placement of the pencil will be different than as a left hander. If you are right handed, make sure the light is on left side. Practice drawing lines first, straight, curved, scribbled lines etc. Then you will be able to make sure that when you draw the final thing your drawing will not be irregular; it will be uniform. Learn how to draw circles and oval shapes with precision, without any falling edges. Shading is a very important technique in art; learn the shades, the correct amount of darkness in the lines and the lightness in the lines at certain points while drawing. Well, these are a few tips that you can use, apart from that, whatever you create will be art. I hope you know what abstract art is.
When you develop art it has to be without errors, without flaws. Make sure that when you develop something other people will not be able to point out the errors. For that, you can first make a rough copy or if you are developing digital art then you can show the rough draft made to the people, then see what they have to point out. More like beta version of your art, out for testing. I hope you understand what I said. Make sure that your art is perfect.
