I agree with you all: "Last Shot" was a great manga. i still have them i believe. it does suck that Studio XD could not continue the story passed issue number 4, though.
if you look at the art for "Last Shot" and compare it to that of "Echo's", you will undoubtedly see the improvement. i would have loved to see Long Vo and the others continue to improve their art, presentation, and story-telling skills with "Last Shot" but it appears that Studio XD may not do that for a while. it's okay, i guess. i can wait- because think, in the meantime, they are getting better at the aforementioned attributes. that is a plus for us because we get to see how they improve by the time they do start "Last Shot" again.
