I like them. I like #2 and #3 overall the best. Here are my opinions since you asked for a critique. It just how I see them....
Not sure about what the little squares are in size, but I think the handles are just a little wide in proportion to the blades. Kind of looks blocky, I would add more curve or slope to the lines in the handle.
My opinion on the pins is this... I think they are too far in from the butt and the front of the scales. I would move the front one forward just a tad. Very small amount and move the back one back just a tad as well. The #2 front pin looks almost perfect for me, but the back needs to go just a little bit backwards.
I think that the back ends is are a little bit too pointing on #2 and needs to look like #3. And then the point on the bottom of the back of the scales looks like a lump to me and doesn't flow.
Most of my hunter blades are similar to #2 in shape. But #3 is so close and it flows really well its hard to say which has the better tip shape. Make both.
Handle suggestions, Micarta, G10, stabilized wood burl, are all good, just make sure you finish them out. It is really the buyers preference. I did two recently that were the same model, but one has hunter orange g10, the other stabilized box elder burl.
I think the patterns are good thing to do and to be to scale and as detailed as possible and most of what I said is just what I would like to see if I was making them or if I was to buy one.
