hey kaspar....hard to estimate but i guess it must be about 3 days+some time to do the renderings. all done next to my regular work, mostly in the evenings. of course i will take part in future challenges but that always depends on if there is enough time to participate...motivation will never be a problem:) by the way, i´d like to get more directions and inspirational material next time (to the whole community) in order to get closer to the desired result. another point would be some critique to the results to see which parts didn´t fit etc. thats very important to learn to get better results next time and something i generally miss a little on grabcad. some constructive critique shouldn´t hurt anybody and it will improve the work. had fun, still happy, always motivated. cheers

Thank you for that Sönke. I agree that technical feedback will be helpful and helps to improve. We are moving in this direction to make it happen.

great.thanks
