Hi Adam,
Showing process is good but to go through all the classic ID steps in a linear way for every project - the process can be a bit more enticing if you show more clearly your intentions, make it a tailored process to your product and show a proof of reaching your intentions in your own way.
Always mention your sources when presenting market research, we also need to see a short summary of demographics.
See if you can spice up your projects more by bringing in ideas about innovation of your own (can we change the entire product archetype, the ergonomics, the interaction at its core?), and specifically tailor the designs to a target market.
Your presentation skills are very good and while we do not see a full proof of concept Return is your best project so far.
Keep on designing!
