As-is, I wouldn't give it a 5. Why? Not ready for table use. No basing is an automatic -1 when I vote. Yes, I know: it's a sculpt. The thing that really popped out at me was that it wasn't painted. Yes, I know: it's a sculpt. Unpainted is nearly the same as poorly painted. Yes, I know: it's a sculpt.
Perhaps if it wasn't held in a base, that wouldn't detract things for me. As silly as the notion of just having a base in the picture being a detriment, it's something I thought of that really bothered me, and maybe a lot of the down votes come from that as well. In other words, having a base in the picture makes it be a vote on "completed figure as shown" where basing and painting are included. Whereas just having the sculpt by itself or on a tool/vise/whatever would equate to "sculpted figure, not painted or based" in my mind.
There's a lot of shine to it, and so the edges just jump out, and overall that makes the picture of it very fuzzy. Fuzzy is not the word I want to use, but I can't think of the word I want. Cluttered, scratchy, blocky, something around that. Maybe the word I'm looking for is "clean". It may be fine in real life, but the pictures make the edges look ragged. Middle top picture is a good example. The edges of the chest muscles (especially the pecs) look a little like someone has been filing on standard modeling plastic (like a model car kit) and has left some of that half melted, half filings grunk around the edge of whatever was being filed.
Maybe a better example would be the bottom right picture. Around the figure's pocket there are some marks. Those are probably meant to be folds, but the picture is a bit grainy and with the high contrast from the modeling compound, it makes it look like stray tool marks. I'm not sure I'm conveying what I'm thinking, so I apologize if my meaning isn't clear.
The background of the picture is gray, and the figure is gray. A black background may have helped. Or maybe colored, or white. I don't know what to do about the shine. If you're planning to cast it or paint it later, then I'm not sure I would give it a shot of clear matte. So... I'm stuck at this point.
Getting past all of that, the figure itself isn't very dynamic. That's just an observation, and a personal opinion. It's not a figure I would buy off the shelf. So I wouldn't adding points to it for that, and maybe others are too. I guess a long story short (too late) is that if you're happy with it, don't worry too much about the votes. Accept it.
