Plus: Nice, interesting font. Even though it´s pretty narrow and compact it does not look squeezed or too crowded.
Minus: #22/#23: The wide format is uncommon for the use as an emblem. The S somehow splits the rest of the letters. We do not like the style of the crown too much, it is too deep cluttered between its jags.#21: we don´t like the greytone, too much associated to (unhealthy and bad smelling) tobacco smoke.
Thank you for your new entries #73 #74 #75 #78 #79 #80 #81
Looks like you really gave some different ideas a hit, very welcome.
Plus: we like the idea of #78 #79 #80 due to its crest-style. #80 is your best entry so far. #81: the crown looks much better now.
Minus: #78 #79 #80: It is not neccessary to have the S of Smoke slinged as this already is part of the emblem. #78 the wordmark gets too small. #73 looks like a bomb ready to explode. #74 reminds on Ying and Yang. Even #75 is still too dark and leaves an unproportional format. #81: the dot at the end of the S is too displaced. Still: this font is really nice.
