Simple, yet nice!
What actually got my intention in this drawing was the shadows made by the sun. You see that everything is well made and that the author spent some time with it. Maybe the only thing I don't understand is the writing that says : "Dia De Calis". Is that spanish or something for "A Crappy Day" ?
Apart from the text and the bike (I see a boy and a girl's bike?), I really think its a good drawing!
