Thank you for your kind advice.
Regarding choosing which path to take, I believe there is a vast difference between Japan and the U.S. In the U.S, I believe engineers have broader chances to improve themselves and are not constrained to the hierarchy built by companies and organization. In Japan however, what turned me off from actually taking the engineering path are the constraints implored by companies and job restrictions. Companies do not have high hope in newly graduated students and, according to many seniors’ experiences, newly students may be forced to do jobs irrelevant to their major (it’s not rare to see students hoping to work in Department A to be put into an odd position in Department B or C, since companies do not recruit for a specific position and instead, recruit to fill in whatever positions that are open).
Compared to many others, my criteria in job choosing is vastly different. I believe I still have further rooms to grow and I should choose a job where I can fly further ahead instead of being constrained to a certain path. Therefore, at the moment, I do not put too much weights on salary and the like, and instead, I put more weight on whether I have the freedom and opportunities to grow to the heights I hope to reach. I also like it more when companies accept my applications for my experience and knowledge, instead of certifications, qualifications, or school names (this is common in Japan. You can apply for an developing job at an IT software even without any prior experiences or knowledge to actual application development.). As such, I found the job of a graphic designer more suitable to what I want to do. Also, I believe the market for graphic designer is wider in Japan compared to that of engineer. There are thousands, perhaps hundred of thousand students graduating from the engineering department each year while there are only a small fraction of students graduating from design or art schools.
As for your advice on the presentation of the designs, I’ve also noticed that I’m making very heavy usage of mockups and have proceeded to try and reduce the number of mockups per project as seen in the latest project. I will try my best to simplify it! Truly thank you for your kind advice.
Also, I’m very happy to hear that I was, to some extent, able to exceed your expectation for a self-taught student. As stated before, I’m a self-taught designer and am currently living in an environment where I couldn’t correctly identify where my skills are standing and on what I could improve as there are no other peers I could find. I can only compare my works to works published on platforms such as Dribbble or Behance, however, some of the works are actually designed by professional agencies, making it very hard for me to get a more accurate grasp. As a result, I would be more than happy if I could identify correctly my weaknesses and strengths to improve myself, not only for job hunting but also for the longer run.
Again, thank you for your kind advice and efforts.
