Over the next two years, you will be creating art at in the end, will need to be displayed as one cohesive show. To keep your show cohesive in nature, you need to either choose an over arching theme/motif. This does not mean all you work has to look the same but it does mean you need to have a common message or narrative, style, color scheme, and/or point of view. There is now wrong or right path but it needs to be something that is personal to you. The more specific the better.
