Aesthetics is about making your Outcome pleasing to look at or use. It is closely tied to Design.
See this external article about Aesthetics in interactive media.
Like a lot of implications, there are links to other implications, such as end users, Usability and Accessibility
Questions that you should consider are:
- Does it look good?
- Is the colour scheme appropriate?
- Is the shape suitable?
- Does it appeal to the right audience?
- Does it follow Design Conventions?
- Does it convey the right image?
