Step 9
Here, I’ve used the cuticle pusher end of the tool to flatten and smooth out areas.  If this end of the tool is turned around, the crease at the knee bend can be defined.  A knife could also be used to do this.  Finally, the edges of the putty are blended into the rest of the model using the flat end of the tool.  You can see this where the green stuff becomes less opaque on the model.
Step 10
The finished join should look like this.  Looking good so far!
