ZuraK. I would suggest to you that you go get some books on values,color, perspective and study them throughout the whole contest. I think you will find that you will improve greatly. Creating artworks is frustrating Without knowlegde of the basic concepts. Here’s some some stuff I wrote that might help you.
It was awfully hard learning for me at the beginning because everything seemed so complicated,frustrating, and all I wanted to do was create cool artworks. It’s not easy work, but if you study hard I have no doubt that you will improve greatly. Good luck
Take some drawing classes so that you become familiar with the basics of drawing. Break down everything you see into simple shapes and colors.
A good technique that doesnt require drawing tools is drawing everything you see in your mind. An example of this would be spending the 3 minutes drawing things around you as you wait for the bus. Figure out what colors and values are right, study little lighting details, and try to pick up anything that will help you further your skills. At first this technique may seem strange but it does help if you constantly use it.
Stop by your local library and pick up some books on drawing and anything you would like to draw. If you want to draw robots get books on trains, cars, anything mechanical. Draw the parts you want to add into your designs many times, over and over again until you can draw them without looking at references. Everything becomes a lot easier if you have a practice routine. Try to figure out a way to practice everyday, maybe 20 minutes in the morning and 20 minutes after work. And dont just spend the 20 minutes drawing anything, Draw from life or pictures. Copying things is the best way to learn. During the weeks days stick to your routine, then on weekends draw whatever you like. Its not bad to draw things from your mind and be creative but for practice have a routine that you always go through. You might start out with 30 minutes of figure study then take an hour break and spend one hour doing a speed painting from a photo, then spend 30 minutes drawing from life, whatever works.
By learning how real life things work it will be easier to create your own imaginary designs. Be sure to practice all the time but not late at night because you wont remember anything you learned that day if you dont get some sleep. The main things you want to practice everyday are perspective, value, color, and design. Dont worry about having the latest art supplies; a 25 cent ballpoint pen or number 2 pencil will work fine. If you only have ten minutes a day to practice, spend those ten minutes drawing things around you such as a cup or building. When doing life drawings dont worry about getting any details in, just get the main shape, values, and perspective right. A good way of not seeing the details is squint a couple times while drawing. Draw everything and anything.
