Great! I've taken a look at my portfolio, and checked if I have something worthy to be called as a "before and after".
The difference I saw may not be as drastic but somehow I felt like I improved over the year -- in terms of composing a photo and doing some enhancing afterwards.
BEFORE - Boracay Sunset taken in February 2017
AFTER - Anitpolo Sunset taken in May 2018
Both were taken using the same camera body and lens, but the "AFTER" photo definitely looked better.
