Thanks guys for the constructive perceptions again, sorry for the late answer but my time to Blender is so much limited in the night hours that need to decide, modeling or checking the forum (the latter is also a pleasure of course!).
Kent I know that Wednesday is not Sunday regarding the deadline :D, but let me add my heroic advanture with the mouse yet, being not too proud to the result and will drop it out soon to restart a new one

Also planning that to my birthday would like to ask a drawing tablet 😀 Basically I am left-handed and not only using mouse but doing the sculpting with right hand actually, which is so a double handicap. While with a drawing tablet on the left side on the computer and in the better hand, with the mouse staying on the right side, it could be maybe a double advantage suddenly 😀
