The only technical thing I note is that the sections that have 179.90 bpm should probably be 180.00 instead. I'm not just basing this on all other bpm in this map being a multiple of 0.25, but also I think the slider at 01:01:37 (1) in Normal seems to begin a little later than it should under 179.90 bpm. Before that, everything is too close to call, but I think I can detect the disrepancy by that point.
Also, how about mega manning the map's skin up a litle? Megaman comboburst pic, for example. Dare I also suggest an hp bar and gameover sound like the ones I use in my Bubble Man wip? (HP bar in tones of blue, of course).
Besides these nitcpicks, the maps are great.
