..yes, probably.
I tried different ways..but I am a beginner and I miss that kind of experience..
I was not able to find the shape that I wanted for the lateral side, so I tried adding more lines..
Now I have the shape I wanted, but I spent to much time to do it.. I really need some experience with MoI, and I have a lot of willing to learn! :)

thank you for your suggestion! :)
