Nafoni: perfect for drawing quick sketches. Lets you draw on top of other images of choice.
Markers is a simple, multitouch, pressure-sensitive drawing app. Some of its features include:
Pressure sensitivity that works with most Android devices: As more of your finger or capacitive stylus touches the glass, Markers will draw a thicker line. NOTE: It may take a minute or two of continuous drawing for Markers to adjust to your device’s touch panel, so be patient! (If your device has an active stylus, like the Galaxy Note or HTC Flyer, the true stylus pressure will be used instead.)
Multitouch painting: Two fingers make two lines, three make three, and so on, up to the limits of your device (typically 5 simultaneous touches for phones and 10 for tablets).
Kid-friendly interface: Every pen size and color is on-screen; multitouch drawing means accidental touches (such as kid hands on the edges of the display) won't prevent any little fingers from painting.
Plays well with others: Share your drawings to other apps, and share images into Markers to draw on top of them.
[New in 1.2] Pan and zoom: By far the #1 most requested Markers feature! Tap the hand tool to switch into zoom mode; use one finger to scroll and two to zoom.
[New in 1.2] Adjustable brushes: Longpress a brush and drag to adjust the minimum and maximum widths.
[New in 1.2] Android 4.4 (KitKat) immersive mode: When you tap the Markers icon to hide the palettes, the status and navigation bars hide too; you can use the entire screen to draw. Tap the icon to show everything again.

Why is my drawing all black when I save it to Gallery? — The drawing is actually on a transparent background, so you're seeing Gallery's black background through it. When you load it back into Markers or send it to another app, you'll see that the drawing is intact. If you'd prefer an opaque background, longpress on a color swatch in the palette to set the paper color.
What's up with the pressure sensitivity on my device? — See http://code.google.com/p/markers-for-android/wiki/DeviceSupport for known issues about individual devices.
