We are definitely on the right track! All three designs have a clean aesthetic.
Entry #1
Second best. Like the use of multiple colors. Good attempt to portray glass. Like the division of name with with bars.
Entry #2
Third best. A tad busy although we like the intersection concept. Least favorite font.
Entry #3
Best of the group...interesting; it suggests art in an elegant way. Like the font. Art Glass Center needs to be together and perhaps slightly less intense colors.
