Thanks for your comment, It will let me do it better nex time! In fact I paint better than I take photos. The miniature was a comission job and i had a maxium price to work, so it was impossible to do all things perfect because all this costs time and money. The mold lines are because the same...the owner of the miniature give it to me with them, and i had no time to remove it...usually in my own miniatures it didn't appears.
This model looks like it was painted by at least two different people. It looks like someone started it and was doing really great, then sold it to someone else who rush finished it, or just wasn't on the same level of painting. Either would work fine with the model, but the fusion of styles makes this model hard to look at.
The Good: Head is fantastic, a 10 for sure. Torso, weapons are top notch, and consistency of color throughout is really great.
The Bad: There are mold lines everywhere on the arms/legs. The highlighting on the arms and legs is awful, and doesn't match the highlighting on the body/head/weapons.
The Ugly: With the good parts mixed in, it makes those gems... horrible. I think I get what you were trying to do, but it just doesn't work. The gradient effect is too jarring. The white spot for lighting effect is good, but doesn't save them.
Now, having said that, either job really isn't that bad. Like I said, either would stand on its own, but the combination doesn't work. Practicing and re-doing the gems with a subtle gradient would really go far to make this model really nice.
