I'm 'fraid what y'er looking at can't be fixed. What y'er seeing there are what normally look like spikes in the mane. Since y'er using a scrolling texture, and these use transparency to work, it shows the full block instead of a spike-which is created by a normal .png texture with no scrolling coding added.
Sorry to say, ye can't do anything to change that. >v< G'luck with the preset, though! 'Tis looking really good so far. Mane looks fantabulous.
