Great easy to read goals and objectives.  

Include more detail on what the partnerships include, not just a list of organization names.

Undefined economic impact information in proposal impact narrative? This could use some detail and strengthening. 

You included a note about in-kind not being included in org budget but it doesn't really explain why you chose not to include any inkind in your org budget?

Accessibility - since you are a choral group, it would help your narrative if you were able to confim that the venues you use have assistive listening devices for audience members.  no mention of this.  The obligation is on your organization, not the venues you use.

Strong:

student apprenticeship program

partnership with SWFLSO and rehearsal/performance venues, business, and media outlets

Good use of marketing dollars with low-cost engagement of monthly webmaster

Volunteer administration

Programs of past, current season and proposed season would be helpful in assessing quality and diversity of content
