@Aislin: your painting is beautiful, i especially like the details in the eyes and the teeth.
This is my first artistic image created in pdn. In the following days I will try to add some shading and a background. I followed
tutorial to draw the wolf.

All shape tools
Currently the mouse cursor hides a portion of the shape you are currently drawing. For example in the screenshot above you can't see where the red line will end.
Suggenstion: hide the mouse cursor when you click and hold down your mouse button to draw a shape.
Line/curve tool
1. If the handles are close to each other you don't know which handle will be selected.
Suggestion: when you hover over a handle show the default cursor ()instead of the "open hand cursor" and highlight the actual handle that is under your cursor (make the other 3 handles semi transparent when you hover over one of the handles).
2. You don't know how a small line changes when you drag a handle because the "closed hand cursor" is covering a portion of it.
Suggestion: hide the cursor when dragging one of the handles.
The artifacts that appear on the outside of the Line/Curve, Ellipse and Rounded Rectangle can be removed by setting the pen's LineJoin property to Round. I think this will get rid of the "small lump" too.

Unfortunately I don't know how to remove the artifacts that appear inside the shapes.

The "expected shapes" were created in Visual Studio:
