5101.3 Assessment
Research Question (Clear, unambiguous) "I intend to examine whether leisure choices are more strongly affected by perceived social class and the general spending patterns of certain demographic communities more so than income."  Okay, so the basic idea here seems to concern the influence of conformity.  
Relevant Literature No discussion of literature.  (Although, to be fair, in each project description, you show some familiarity with the literature and a good effort to look at some of the relevant findings)  Given the nature of the ideas, you would probably be interested in sociological studies concerning culture or art that stress the ideas of Bourdieu.
Causal Interpretations (clear, all parts defined, mechanisms, controls, plausible) "I hypothesize that the social pressures or common tendencies of a particular demographic group cause certain leisure choices, independent of income or education level."  Okay, this is a pretty clear causal statement that individual cultural choices depend on social location.  
Data (variables, sample, comparison) While the description of data to be used seems thoughtful, it is not apparent how it can translate into an analysis.  The counterfactual might be how members of a "demographic group" would spend their leisure time in the absence of influences toward cultural or network conformity.  How do you think you can get at this with the data being considered?
Research Value Insights into the significance of conformity are clearly theoretically valuable, although this is not what you mention.  As for the goal of understanding why some kinds of people do not attend museums, it is not clear that showing it is because others in their milieu also do not actually translates into a policy insight.
