Don't worry about the camo pattern on the bow, as long as it isn't shiny, like a target bow, the pattern is not that important.
4lbs isn't that heavy for a hunting bow, a little weight adds stability and usually makes for a quieter bow on the shot.
All the bows you've selected are nice choices.
My biggest concern for you, seeing as you don't seem to have access to a bow shop that can tune your bow, is to get a model with very good quality strings. If the strings stretch, the bow needs to be put in a press and the strings need to be twisted some more to get them to the right length again.
(Guys, maybe some of you haven't noticed, what we have here is a young female shooter. She most likely will not be able to handle the heavier draw weights some are suggesting.)
A 40-50lb bow would probably be a good place to start. With your short drawlength (DL for short) you will want a bow that has very good performance in a short DL. I would really suggest you check out the womens forum on this sight. There are a lot of ladies there who have a great deal of experience with different bow models and what works for them. Some bows are designed to perform better at shorter DLs then others. The Bowtech Equalizer comes to mind as one such model.
Come back to this Hunting Forum to keep asking questions, we love to help. I admire your ambition in trying overcome all the obstacles of a young lady in Scotland who wants to hunt big game with archery equipment.
