Even though I might not have a great many mini\'s on my gallery, I\'ll try my best and give some tips
1: Always water down the paint and use serveral thin coats instead of 1 thick, on my shaggoths skin, it took abaout 13 tanned flesh coats, but its smooth and a smooth basecaot makes highlighting much easier
2: Use a good brush with a sharp point
3: Try and find a colorscheme that suits you and the mini, be it dar or light, nmm or real metal, evil or good, etc etc
4: Do a nice base, a striking base might give you an extra point or 2
5: Pay attention to all parts of the model, and dont stop untill your satisfied
6: Make sure you add \"that little extra\", be it glowing eyes, blood on the weapons, a characteristic tatoo, a jewel or anything you might lay your eye on, that too might just make the model interesting enough to add yet another point.
7: Conversions are always a great way to make a model more interesting, just a weapon swap or headswap or repositioning, anything counts
8: Make sure the colorscheme fit with the base/rest of the mini. Having a goblin (green) with a white coat (white) on a completely white base (snow) makes a dull overall weiv, better mounting such a model on a dark base, just to make it stand out.
9: If a area of the model dont turn out as you want it, it might be, for example, too bright, then dont re-paint it, using thing glazes you can tune the brightness down and still have a smooth surface that doesnt have an inch thick coat of paint on it (exaggeration)
10: Practice, practice and even more practice, no-one can get better at anything without practice, and it takes time too, so just be patient and you\'ll have your 7:s, promise =D
Cheers
Erik
