Looks great! Like the sepia type color. Good subject, water is always good with IR shots. You can also bump up the aperture and thatll let more IR collect to darken the clear sky parts more, and itll mirror the water out more. Water and glass become opaque in heavy IR and almost mirror like. Ir light penetrates some materials deeper than normal light. Skin, fabrics and other things can become translucent. Tripod, obviously is required, but if you have one on you youre set. Also magenta isnt being let in though the filter, Its the common color most digital cameras seem to display IR as. The only color really getting through is deep, deep red, which is more IR-ish than visible-ish. IR has no color of its own. Id go ahead and add some more contrast in PS, bring out those clouds and distant branches and water ripples. Have fun:)
