Hi, you got new subscriber.
So, my opinion : The coloring is good. The action scene is good too, I can get the feels and it didn't confuse me as in 'where the heck the MC is now?' but I can clearly see and follow their fight. Nice, you have talent on making action.
The font however, the text and the font is clear on desktop but on mobile they are hard to read. So well, make it more read-able on mobile version next time?
Otherwise, it's good. Keep on making comic.
