So many people get intimidated when they are asked to draw. Some say its hard. Well it is really BUT it can be learned. I started learning how to draw by just getting my pencil and paper and started with lines and looking at objects as if they were made of hundreds of lines. That is basically how you start really.
There are so many tutorials and books you can use as reference to learn and really be good at drawing. Drawing is a great way to release your creative energies. It is also a great way to put ideas together. You can do rough drawings and who knows it may be the spark you need to finish that design project.
If you want to learn how to draw, I believe learning Manga style is the best start. It is almost realistic, yet it is flexible and allows you to just have fun making characters.
Here is a video on how to start: A step by step guide to drawing the Manga Eyes. Most drawings start really with the eyes of the character. The eyes usually set the mood of the character. The illustrator here even has a site and has books that can help you develop your skills. Mark Crilley check it out if you want to learn more. So now, get your pencil and paper out and try it!.
