They may have a bit of an over processed look. The question in my mind is are they over processed because they are over processed or because (and I didn't say anything above), these are both infrared. Because they are IR, they will have a bit of a dramatic look depending on the subject. If they are over processed, which of these would you say that it is?
FWIW: I'm working right now on trying to do a number of IR photos where the emphasis isn't on their being IR -- just creating beautiful photos where the fact that they are IR is secondary. (IMHO, much of the IR is done because of the novelty of IR, not to create a beautiful piece of artwork.)
