The default skin's not so bad in general, but I have to agree that a smaller/transparent hitburst might look cleaner than the default one. I've got nothing against the default skin, but after seeing Reisen's Top Korean players vid, I think the transparent hitbursts look better for a video, especially a Top X video where the maps are gonna end up covered in them. Then again, I suppose the hitbursts give the maps that "epic" feel Neruell pointed out, especially for the less skilled players who wouldn't really be able to read what's going on without them.
Great video btw, I really liked the intro, and lol Big Black Cookiezi entrance. Too bad not many people were interested in commentating.
