I have entered many challenges and find they are a means to bring out the best in an artist. You have to focus on a theme and guidelines but keep your style. Great avenue to broaden your talents.
I am working on a challenge right now. It is a 3"x5" notebook that is to be designed with the theme... Everyone You Know. Now.. it will tour the East Coast and is for sale.
This is a great way to get exposure for yourself and for your art...
Now for an interesting challenge I entered... creating a postage stamp.. I had to have two identical stamps and was given the letter A for the theme... That may have started my career for the creators of the challenge selected my entry to be used in their book. It is now in a museum on the East Coast...
Yes... you have to get into the little things too...... to be an artist...
