Every once in a while Dogwaffle's creator sends me some cool sketches by other artists to play with.Because i have a license for the Pro version they are free for me to use.
They're free for you to use as practicing material for coloring, tracing, enhancing. If you want to make commercial use of your artwork derived from these you will need to please contact Jon at the Dogwaffle website.

Some pretty good sketching there Rod.

The bottom two has alot of detail in them

They are not mine, as i said they are from Jon.
Feel free to color them and play with them.I thought it would be fun.

Great sketches!!! Thanks Rod.

That's a nice one Lorri!
You are very welcome O.If i get any more in the future i will be sure to share them.

How about a little colored pencil effect?
Either take another image and place it on top in screen mode, or create a transparent layer on top and paint or sketch in screen, or another layer mode.This one has the Rodilius puppy image behind it.

Last image is great for working with layers.

Fun!

Is that a checkered pattern behind the original O?
Pretty nifty looking!

They are all great for using in Inkscape also.Just use the tools to create each different shape and color them in with fills, patterns, or gradients.Then you can scale them to whatever size you want.
You could make some pretty cool Halloween posters for parties!

No, it's a stock image from Stock Xchng. I scaled it to the dimensions of the drawing.

I would have never guessed that was the bg image. Great!
