Hi fermat, thanks for sending all your ideas. i like 102 the best, a little bit fragile. in holland we have a saying " it stands like a house" " het staat als een huis" that means. it is very stable. that also has to radiate in logo.
furthermore find it difficult to chose the wright color. it has to be warm, inspiring and strong. maybe forest green, red to pink purple and whit grey/taupe.
