I can't draw jack. Not even a little bit, and while I cannot tell you it doesn't matter, because it does, just not as much as you think. There are literally thousands of places on the web to acquire open licence vector art and photos. There are even obscure sources like public domain advertising and such to add originality. Probably millions of fonts also. At their core designs break down to these two components in most cases. It all just digital manipulation of one or both. Actually the ability to effectively use programs like photoshop and illustrator has proven to be a greater advantage in most cases. I would love to be able to draw but i can't so I just work with what I have. You can also. Take some figure and drawing classes at your local community college. Study color theory and all that. It will help you a lot, but don't let a lack of drawing ability stop you.
