There\'s a few things that might be worth noting about the voting. First, it really is Cool MINI or Not, for most voters it\'s not just about the painting level. Sculpts from the more popular manufacturers (Games Workshop) and new and different sculpts (usually small boutique companies) will tend to get higher scores than older sculpts or others people don\'t find \'special\' in some way. Ral Partha, Reaper and other role-playing oriented minis often score lower.
There are a few things many voters will mark down for. No basing or just a basic built-in integral base is one of them. A lot of voters expect to see nicely based minis on standard round or square bases. Other things people will mark down for are failing to retitle the submission so it comes up \"Another Mini\" and a few other things, but you aren\'t doing any of those so I wouldn\'t worry about it. Interestingly I think most voters try as hard as possible to look past photo issues and give things the benefit of the doubt. Your photos aren\'t bad, but adding a light or two to get rid of the harsh shadows couldn\'t hurt.
I think your painting is pretty solid. I took a look at the orc in your gallery also, and really like him. I think the anti-paladin suffers a bit from being kinda blah (just cloak, armour and skulls), where the orc has a bit more going on with a bit more detail on the sculpt and the way you added rust to the blade and such. He also has the benefit of the colour contrast between the green skin and red cloth.
When people mention contrast, it might help to remember that there\'s different kinds. I think most people are talking about the depth of shadows and lightness of highlights in this case. (And while it\'s really hard to do when painting and I understand why you pulled it back, it\'s almost impossible to have too much contrast. Paint something to the point where you think it\'s way too much, come back here and post again and see if anyone else says it\'s too much. They probably won\'t.)
But it\'s also helpful to have other kinds of contrast. There\'s colour contrast like red clothes/green skin on your orc. You can add a bit of that to the other fig by using a touch of red paint/ink in the shadowing of the armour. Painting different areas darker or lighter also helps bring stuff out on a mini and give it more punch. In the rear view of the orc his pouch is much lighter than the other colours on the mini which helps it stand out. If you used that same colour on the leather under his helm it would draw attention up to his face and keep the viewer\'s eye moving.
Also note that I\'m not suggesting you start painting GW minis on big exciting bases and so on, I\'m just saying a lot of voters score higher if you do that, so if you choose not to keep in mind that a lower score isn\'t necessarily all about the painting. I think if your orc were GW and had a proper base he\'d be scoring in the 7s.
