I can tell by the accuracy and beauty of the hero symbols (sentai/rider alike) on your channel that it takes ALOT of hard work to reproduce for your own personal enjoyment as well as others.
It pains me to see that you have water-marked your latest creations starting from the Zyuranger ones and Wizard Defend to the current tokusatsu shows airing.
I know that you are frustrated that people are using your work and not giving you credit (or even taking the credit for themselves), but please don't water-mark these master pieces because they ultimately don't look good if you do. The art itself will suffer as a result.
So please, if you could, re-upload the water-marked images with non-water-marked versions and continue to make hero symbols the same way you've been doing before you started to water-mark them.
