Here is something cute that is going to be incredibly easy to draw. Since I haven't done anything cool lately, I thought I would show you "how to draw a heartbeat", step by step. This simple pulse line came out so awesome, yet the concept is so simple. Drawing a heartbeat is as simple as writing 1, 2, 3. there is no big deal to getting it done but instead of drawing a series of spikes, I went ahead and draw a heart in the middle, then it flows out to be a spiked heart or pulse rate. This would make a cool tattoo design for around the upper arm, or wrist. If you have been waiting for a cool concept tattoo design that is almost like an illusion, here it is. I do hope you have fun with this tut, I know I did making it.
